چکیده

This work presents a design technique to implement miniaturized cross-coupled bandpass filters in inline physical configurations based on triple-mode resonators. Triple-mode resonances are obtained by using integrated coaxial-waveguide cavity They consist of two coaxial conducting posts placed the sidewalls rectangular waveguide cavity. In proposed triplet, transmission zero (TZ) can be positioned at any sides passband simply locating either same wall or opposite walls Coaxial-to-waveguide mode coupling is implemented means screws, which adds flexibility terms tuning easiness. Three 9.9-GHz proof-of-concept prototypes corresponding third- and sixth-order designed electromagnetic-simulation level. Furthermore, triplet with TZ below manufactured characterized experimentally validate engineered 3-D RF filter principle its underlying theory.

Design of miniaturized bandpass filters using quasi-lumped Multilayer Resonators

A novel design procedure for a compact multilayer bandpass filter is proposed and examined. The filter is realized using quasi-lumped multilayer resonators. Based on the orientation of these coupled-resonator pairs, a second-order bandpass filter is realized with transmission zeros. In order to achieve a low external quality factor, i.e., a wider filter bandwidth, different types of feeder real...

Compact Differential Bandpass Filters Based on Coupled-Line Resonators with Improved Performance and Miniaturized Size

Two compact differential bandpass filters (BPFs) based on coupled-line resonators and loaded capacitors are proposed in this work. By properly designing the coupled resonator and the loaded capacitance of original filter model, differential-mode (DM) passband responses and commonmode (CM) rejection can be obtained. For validation, two differential BPFs named Filter I and Filter II are discussed...

Circular Waveguide TM11-Mode Resonators and Their Application to Polarization-Preserving Bandpass and Quasi-Highpass Filters

Circular waveguide filters with improved performance are presented. They are based on TM11-mode resonators which permit the filter to be smaller than standard TE11-mode filters, preserve all polarizations due to rotational symmetry, and are flexible with respect to the design of bandpass or highpass filters. In order to demonstrate their advantages, they are compared to a standard TE11-mode des...

Compact Microstrip Bandpass Filters Using Triple-mode Resonator

Step-by-step procedures for designing a third order bandpass filter and a sixth order bandpass filter using a triple-mode resonator are described in this paper. The triple-mode resonator is a square open-loop resonator with an open circuited stepped-impedance stub and a grounding via located at the symmetrical plane of the resonator. The equations for approximating the resonant frequencies of t...
