A miniaturized interdigital microstrip bandpass filter
IEEE Transactions on Appiled Superconductivity, 1999 A 2.4 GHz three-stage microstrip bandpass filter was designed using a miniaturized interdigital capacitor structure to reduce the configuration in size. The filter was simulated by a finite element method software and then fabricated using TBCCO superconducting films on 20 mm/spl times/20 mm/spl times/0.5 mm MgO substrates.

Coupling Matrix Representation of Nonreciprocal Filters Based on Time Modulated Resonators [PDF]
, 2019 This paper addresses the analysis and design of non-reciprocal filters based on time modulated resonators. We analytically show that time modulating a resonator leads to a set of harmonic resonators composed of the unmodulated lumped elements plus a ...

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.
