Заглавие : The effective permittivity of an anisotropic composite of spheroidal particles in a dielectric matrix
Место публикации : Tech. Phys. Lett. - 2022. - Vol. 48, Is. 3. - P.110-114. - ISSN 10637850 (ISSN), DOI 10.1134/S1063785022040058

Аннотация: The concentration dependences of the effective permittivity have been obtained for an anisotropic composite consisting of a dielectric matrix filled with codirectional particles in the form of oblate or prolate ellipsoids of revolution (spheroids). The calculation has been made by solving numerically a system of coupled quadratic and integral equations obtained using the rigorous modification of the quasi-static Bruggeman theory. It is shown that the traditional simplified modification of the Bruggeman theory, which is widely used for calculating anisotropic composites, leads to errors of different signs for electromagnetic waves of the longitudinal and transverse polarizations relative to the spheroid axes. The dependences of the errors on the particle concentration are nonmonotonic and extrema observed in them can exceed 100%. The positions and values of the extrema depend strongly on the ellipticity of particles and the contrast of their permittivity with that of the matrix.

Заглавие : Features of characteristics of second-order bandpass filters based on half-wave and quarter-wave microstrip resonators
Место публикации : Russ. Phys. J. - 2022. - Vol. 65, Is. 2. - P.276-286. - ISSN 10648887 (ISSN), DOI 10.1007/s11182-022-02633-1

Аннотация: A comparison is made of the characteristics of bandpass filters consisting of two interacting resonators, which are either half-wave or quarter-wave segments of microstrip transmission lines with the same widths of strip conductors. Plates with a thickness of 0.5 mm made of TBNS high-frequency ceramics with a relative permittivity ε = 80 were used as substrates for microstrip structures. The structures having a maximum coupling region of the resonators and the maximum value of their coupling to external ports with a wave impedance of 50 Ω were studied. The filters were tuned by selecting the gap between the strip conductors so that the maximum reflection level in the passband was equal to –20 dB. Electromagnetic simulation of 3D models showed that the fractional bandwidth of filters based on quarter-wave resonators is almost 2 times wider than the bandwidth of filters based on half-wave resonators, and this fact is confirmed by the measurement results. The discovered effect is explained by twice the characteristic impedance of a quarter-wave resonator relative to a half-wave one.

Аннотация: A half-wave microstrip resonator design with an irregular strip conductor short-circuited to the screen by its ends has been investigated. Based on the resonances of the first two oscillatory modes of this resonator, a miniaturized second-order filter with a fractional bandwidth from 40% to 90% has been implemented, which has a wide high-frequency stopband. A prototype of the designed eight-order filter based on four dual-mode resonators with a passband center frequency of 2 GHz and a fractional bandwidth of 40% has been fabricated on an alumina substrate 45.0 × 10.5 × 1.0 mm3 in size with a permittivity of ε = 9.8. The filter frequency response slopes are extremely steepness due to two attenuation poles located on the left and right sides of the passband. The experimental characteristics of the prototype are in good agreement with the data of the numerical electromagnetic simulation of the 3D model of the filter.

Аннотация: New microstrip designs of bandpass filters have been developed on the basis of a low-pass filter with some or all of the sections of the high-impedance microstrip lines connected to a screen by stubs. The filters exhibit the high frequency selectivity and their fractional bandwidth falls within the range of 30–150%. An experimental sample filter with a passband center frequency of 2 GHz and a fractional bandwidth of 70% formed on a 1-mm-thick alumina substrate has a substrate area of 46 × 21 mm. It is shown that the measured frequency responses of the filter are in good agreement with those calculated using the numerical electrodynamic analysis of its 3D model.

Microstrip structures, which are studied theoretically and experimentally, use one multimode resonator and a pair of single-mode resonators. There is fairly good agreement between the calculated data and the data taken on the experimental sample. The relative bandwidth of the manufactured microstrip filter is 60%.

Аннотация: A new miniature design of a highly selective lowpass filter based on a suspended substrate with a two-sided stripline pattern has been developed. The filter frequency response slope (cutoff attenuation rate) and stopband attenuation depth are determined by transmission zeros, the number of which is equal to the filter order. An experimental prototype of a fifth-order lowpass filter on 0.5-mm-thick alumina substrate with dielectric permittivity ε = 9.8 has been synthesized with the aid of numerical electrodynamic analysis of a three-dimensional model. The cutoff frequency of the filter passband at a –1-dB level is fc = 1.75 GHz. The stopband width at a –100-dB attenuation level reaches 4.4fc.

Аннотация: A new construction of a lowpass filter was developed based on a two-dimensional microstrip electromagnetic crystal, which had a steeper slope of the frequency response as compared to a filter consisting of a one-dimensional microstrip electromagnetic crystal. The investigated lowpass filter construction is characterized by a high workability and ease of manufacturing. Electrodynamic numerical simulation of the 3D model of the considered microstrip structure agrees well with the experiment, which allows conducting parametric synthesis of devices with the required properties using a personal computer.

Ключевые слова (''Своб.индексиров.''): bandpass filter--meander--stopband
Аннотация: The constructions of bandpass filters with irregular quarter-wave resonators are suggested. Due to the high jump of the wave resistance in line segments the microstrip structures have extended high-frequency stopbands. Different alternatives for the location of resonators with a conductor in the form of meander on dielectric substrate were studied. In this regard the use of codirectional resonators helps to improve frequency-selective properties of microwave filters. © 2017 IEEE.

Аннотация: An original microstrip resonator design with a strip conductor split by a slot at one of its ends is investigated. It is demonstrated that at the optimal slot sizes, when the eigenfrequency of the second oscillation mode hits the center between the first and third oscillation modes, the resonator can work as a thirdorder bandpass filter. The structure formed from only two such resonators electromagnetically coupled by split conductor sections is a miniature six-order wideband filter with high selectivity. The test prototype of the filter with a central passband frequency of ~1.2 GHz and a passband width of ~0.75 GHz fabricated on a substrate ~(45 × 11 × 1) mm3 in size with a permittivity of 80 is characterized by minimum loss in a passband of 0.5 dB. The parametric synthesis of the filter structure was performed using electrodynamic analysis of the 3D model. The measured characteristics of the test prototype agree well with the calculated data.

Аннотация: Ten microstrip bandpass filters with wide high-frequency stop band are investigated with the help of the numerical electrodynamic analysis of 3D models. From each resonator bandwidth of the offered filters tuned with a relative width Δf/f0=20% is formed by one lowest oscillations mode only. However at all microwave devices the extended high-frequency stop band is observed due to large leap of lines portions wave drags. Build-up of number of resonators in filters up to 6 order is resulted by growth of the steepness of slopes bandwidth and gain suppression of power at frequencies of stop bands. The width of high-frequency stop band at miniaturization of microstrip devices is reducing.

Ключевые слова (''Своб.индексиров.''): bandpass filters--crystal filters--microwave filters--photonic crystals--poles--resonators
Аннотация: The design of 8-order band-pass filter based on 2-D photonic crystal is suggested. Strip conductors in all dual-mode resonators are in the form of irregular rectangular frame with a gap and are connected at certain points with the ground. At optimal placement of such resonators on a substrate attenuation pole is observed on the amplitude-frequency characteristic of the filter, near low and high bandwidth slope that significantly improves its frequency-selective properties. The change of gap between input and output resonators allows to control the frequency of these poles.

Ключевые слова (''Своб.индексиров.''): resonators--frequency-selective properties--high frequency hf--microwave structures--multimode resonators--quarter wave resonators--relative bandwidth--single-mode resonators
Аннотация: A new approach allowing to improve frequency-selective properties for a fixed order of N filter is suggested. In all the studies, conducted with the help of numerical electrodynamic analysis of 3D models of microstrip filters based on a multimode resonator, the same substrate with dielectric constant ϵ=2.8 and thickness h=2 mm (material - FLAN) was used in calculations. The central bandpass frequency of microwave structures f 0≈1.4 GHz was registered and as well as relative bandwidth Δf/f o≈80%. The strip conductor of central multimode resonator in six studied filters of the sixth and eighth orders has the shape of an irregular meander being electromagnetically connected with four single-mode resonators, a pair of which is located to the left of it, and the other pair is to the right. It is shown that in single-mode quarter-wave resonators building-up the number of portions of identical parallel strip conductors, connected to a screen at one end and connected with each other by a strip conductor jumper, can increase the power of suppression at low-frequency stop band by more than 15 dB, as well as near high-frequency slope of passband by more than 10 dB. Therefore, the level of maximums of return losses in the passband of wideband bandpass filter ranges within a few dB.

Аннотация: Construction of microstrip bandpass filters is suggested on the basis of 2D electromagnetic crystal consisting of P horizontal and K vertical rows of resonators. Adjacent vertical rows of resonators are connected by additional m K-1 resonators arranged above and below the outside 2D crystal. Parametric synthesis of six bandpass filters based on crystals with the dimension of 1×2, 2×2, 2×3, 3×1, 3×2 and 3×3 was conducted with use of electrodynamic numerical analysis of 3D models in studied constructions. While calculating substrates with relative permittivity ε=80, h=1 mm thick were used, in this connection, center frequency of bandwidth was registered as follows - f 0≈1.0 GHz, as well as their relative bandwidth Δf/f 0≈20%. High frequency-selective properties of the filters are connected not only with the increase of their N order, but also with the presence of amplitude-frequency characteristics of power attenuation poles located near the bandwidth.

Ключевые слова (''Своб.индексиров.''): amplitude frequency characteristics--connection coefficients--glass substrates--high contrast--high frequency hf--periodic interchange--relative bandwidth--ultra-wideband filters
Аннотация: Multilayer photonic crystal structures with bleaching layers are being investigated. In order to calculate the characteristics of ultra-wideband filters on their basis, T-lines lossless model was used. Amplitude-frequency characteristics for the synthesized filters of 5th, 11th and 17th orders are given. It is proved that by a significant increase in filter N order, the difference between the connection coefficients of central resonators' layers' becomes negligible. This makes it possible to develop 27-order filter, in which almost half of the layers are realized by periodic interchange of only two identical high-contrast materials. The investigated band-pass filters, including the ones on a glass substrate, have high frequency-selective properties at a relative bandwidth of 80%.

Аннотация: The diplexers based on 2D electromagnetic crystal are investigated with the help of the numerical electrodynamic analysis of 3D models. The input half-wave resonator has rolled up strip conductor in the claimed microstrip designs tuned with nearly adjacent bandwidths. It allows to coordinate channels rather easily. Such resonator in the first two-channel device at the same time interacts with pair of quarter-wave resonators having strip conductors in the form of the Russian letter «П». In the second two-channel device it interacts similarly, with pair of resonators with strip conductors in the form of a letter «Ш». Build-up of number of periodically located rectangular portions of strip conductors in adjacent resonators allows to increase in proportion number of the resonances participating in formation of both low-frequency, and high-frequency bandwidths. At the same time in amplitude-frequency characteristics of diplexers growth of the steepness of slopes of adjacent bandwidths and gain suppression of power at frequencies of stop bands are observed. © 2016 IEEE.

Аннотация: New multimode irregular microstrip resonators and designs of wideband bandpass filters based on them are being theoretically and experimentally investigated. A central multimode resonator electromagnetically connected with single-mode or two-mode resonators at the input and output of a structure are used in the developed filters. It is the first experience giving the possibility of combining inherent frequencies up to six lowest modes of oscillations, which are involved in the formation of the bandpass of the multimode resonator. Strong interaction of oscillations modes leads to its significant extension.

Аннотация: The natural frequencies of the multimode microstrip resonator «hairpin with stub» were investigated from its constructive data. Application in the resonator of the stub allows not only to observe on amplitude-frequency characteristic the poles of power attenuation, and also to considerably reduce frequencies of all its even modes of oscillations. At the same time frequencies of odd modes don't change. It allows to use in addition two resonances participating in formation of expanded bandwidth of the filter based on such resonator. High frequency-selective properties of such design are caused not only the poles of power attenuation located as near low-frequency, and high-frequency slopes of bandwidth, but also wide stop band. © 2016 IEEE.
