Abstract

Using slow‐wave transmission line ring resonator and square‐patch element, a novel compact dual‐mode microstrip bandpass filter is developed in this article. A filter having a 3% bandwidth at 2 GHz is designed, fabricated, and measured. The design procedure is given, and the mode‐splitting characteristic and impact of the patch element on the performance of the filter is investigated. The proposed filter has a smaller size compared with conventional dual‐mode bandpass filters at the same central frequency. This compactness is about 35% for the fabricated sample. © 2011 Wiley Periodicals, Inc. Microwave Opt Technol Lett 53:656–659, 2011; View this article online at wileyonlinelibrary.com.

## Abstract A novel design of a compact bandpass ring slot filter for achieving dual‐mode operation is proposed and experimentally studied. By using an arrow‐shaped slot structure as a resonator, the resonant frequency of the proposed filter is significantly lowered, which can lead to a large filte

A novel dual-mode microstrip filter operating at 900 MHz is proposed using degenerate modes of a microstrip-loop resonator. The resonator structure that is formed of meandered microstrip-line elements has a smaller size than the other dual-mode microstrip resonators in the literature. The dual-mode

## Abstract A compact dual‐mode bandpass filter (BPF) using equilateral triangular slotted‐patch resonator is proposed, which has the advantages of compact size, low insertion loss, and good passband selectivity because of two transmission zeros located at the low and high stopband. A demonstration
