Design of Dual-Bandpass Hybrid Waveguide–Microstrip Microwave Filters [PDF]
IEEE Transactions on Microwave Theory and Techniques, 2008 A simple dual-bandpass filtering structure is pro- posed. The filter is implemented by means of a new hybrid waveguidemicrostrip technology. The novelty of the structure is that it combines two standard printed microstrip coupled line resonators, with a resonance of the base waveguide cavity, to implement a dual-band operation. Important aspects about

Design of a Microstrip Filtering Antenna for 4G and 5G Wireless Networks
Journal of Telecommunications and Information Technology, 2023 The filtering antenna provides both radiation and filtering features and is an important component for the RF front-end of wireless devices. The main function of a filtering antenna is to reject out-of-band signals, thus reducing the interference from ...

Compact Microstrip Filter With Third-Order Quasi-Elliptic Bandpass Response
IEEE Access, 2018 In this paper, a novel microstrip filter is proposed, which can realize a third-order quasi-elliptic bandpass response. In order to reveal the physical mechanism of the microstrip filter, a lumped-element equivalent circuit is set up and the equivalence ...

Microstrip Diplexers With Double-Stub Bandpass Filters
, 2011 This paper presents a microstrip diplexer using two Double-Stub Band-Pass Filters (DS-BPFs), composed of several double-stubs connected to a main microstrip line. Each DS-BPF has a null at the center frequency of the other. Therefore, these types of filters are suitable for diplexers with two near frequencies.

A NOVEL MICROSTRIP LC RECONFIGURABLE BANDPASS FILTER [PDF]
Progress In Electromagnetics Research Letters, 2013 In this paper, we propose and develop a novel reconflgurable bandpass fllter based on microstrip LC resonators. The equivalent circuit model of the proposed fllter is presented. The fllter can be reconflgured by tuning the capacitance of the microstrip LC resonators.
