Заглавие : Design for a self-packaged aLl-PCB wideband filter with good stopband performance

Аннотация: A new design of a self-packaged all-PCB wideband filter based on the cascade connection of high-pass and low-pass filters is presented. The novel low-pass and high-pass quasi-lumped filter structure differs from the known ones by the existence of cross-coupling between elements producing transmission zeroes at the desired frequency. It is shown that high order structures make it possible to design a wideband filter having the number of transmission zeros in the low-frequency stopband equal to the order of the applied high-pass filter and the number of transmission zeros in the high-frequency stopband equal to half the order of the low-pass filter. An implementation of two-layer metallization of the capacitor plates made it possible to manufacture all three types of filters using the common technology of multilayer printed circuit boards with a good coincidence of the characteristics of the model and the fabricated filters. The filter fabricated using materials with a rather low-quality factor (F4BM/RO4450B/RO4003C) has demonstrated a good performance: the central frequency is 0.99 GHz, the 1 dB fractional bandwidth is 152%, the minimum in-band loss is 0.3 dB, the selectivity (Δf30dB/Δf3dB) is 1.21, and the 40-dB stopband width is 6.16f0.

Аннотация: The paper is devoted to simulation, designing and fabrication of a microstrip 5-order bandstop rejecting filter. The bandstop filter uses classic schem, e.g. it consists of a microstrip through (common) line whose ends serve input and output ports. In the vicinity of the line a number of microstrip rejecting resonators locate, in our case five S-shaped resonators. They electromagnetically interact with the line, that forces signals, having frequenscies, bieng equal to the resonant ones, to reject (reflect) from a device. Dielectric substrate of the device has thickness 1.0 mm, and other sizes are 44.0×20.0 mm 2 . The filter described in this work has shielding. In a band 1480 MHz …1499 MHz rejection exceeds 50 dB. Transmission bands at a level –2 dB are 0…1437 MHz and 1563 MHz…3000 MHz lower and upper correspondingly. Return loss in the passbands does not exceed –16 dB (VSWR≤1.4). Good agreement is observed between simulated and experimental data. Fabricated filter has small size.

Аннотация: A new design of a self-packaged all-PCB ultrawideband filter based on the cascade connection of high-pass and low-pass filters is presented. The novel low-pass and high-pass quasi-lumped filter structure differs from the known one by the existence of cross-coupling between elements producing transmission zeroes at the desired frequency. The filter fabricated using materials with a rather low quality factor has demonstrated a good performance: the central frequency is 0.99 GHz, the 1 dB bandwidth is 151%, the minimum in-band loss is 0.3 dB, the selectivity (Δf 30dB /Δ f 3dB ) is 1.21, and the 40 dB stopband width is 6.10 f 0 .

Заглавие : Quasi-lumped multimode stripline resonator and filter with good stopband performance
Место публикации : Microwave Opt. Technol. Lett. - 2020. - Vol. 62, Is. 3. - P.1183-1187. - ISSN 08952477 (ISSN), DOI 10.1002/mop.32173

Аннотация: A novel multimode resonator is proposed, containing five resonant modes that are incorporated in the passband forming. The structure is based on a dielectric substrate suspended in a metallic case that allows solving the problem of electromagnetic compatibility. Due to features of the resonator's structure, several higher modes do not excite that significantly improves the performance of the filter's stopband. The resonator advantages are proved on the bandpass filter (3.1…10.6 GHz) with a small overall size (0.19λ0 × 0.11λ0 × 0.11λ0) and a good stopband performance (first spurious band locates at 29 GHz and suppression is 70 dB).

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.

Ключевые слова (''Своб.индексиров.''): fourth order--microwave bandpass filter--stopband--stripline resonators--suspended substrates--wide upper stopband
Аннотация: A method aiming to widen the upper stopband in a microwave bandpass filter based on two-conductor suspended-substrate stripline resonators is described in this letter. Applicability of the method is illustrated by simulating and fabricating fourth-order filter that has a very wide upper stopband: Δfstop/f0 = 7.92 measured at a level -50 dB, which is achieved because the widths of the inner resonators in the structure are 1.4 times greater than that of the outer ones.

Ключевые слова (''Своб.индексиров.''): filter--frequency selective surface--grating--multilayer design--polarizer
Аннотация: We propose a multilayer bandpass filter in which every resonator consists of two identical dielectric layers separated by a grating of parallel strip conductors. The resonators themselves are separated from each other and from the ambient space by gratings of strip conductors with an axis orthogonal to the axis of the gratings inside the resonators. The proposed filter construction acts at the same time as a polarizer. The device frequency response computed with use of the provided simple formulas is in a good qualitative agreement with numerical electromagnetic analysis of its 3D model.

Ключевые слова (''Своб.индексиров.''): electromagnetic fields--plants (botany)--density of photonic state--long wavelength--photosystems--plant leaves--soft modes--stopband--two bands--water dissociation--transfer matrix method
Аннотация: Using data on the structure of plant leaves, specific features of light propagation in biophotoniccrystal structures have been established by the transfer matrix method. Splitting of the stopband in two bands has been found. The density of photonic states and the electromagnetic field value have been calculated. The occurrence of two photosystems (splitting of the stopband in two bands), the peculiarity of the long-wavelength quantum yield and its enhancement (Emerson effect), and water dissociation in the soft mode due to an increase in the electromagnetic field on the layers are explained.
