Abstract

This article presents a microstrip diplexer with 2.4/5.2 GHz response by using the simple coupled resonators for reducing the circuit size. Stepped impedance resonator (SIR) can be shared by the two filter channels for the designed diplexer if their fundamental and the higher order frequencies are properly assigned. The diplexer has only three simple resonators which can achieve both two good passbands and effectively reduce the circuit size. Measured results of the proposed diplexer have a good agreement with the electromagnetic (EM) simulated results. © 2007 Wiley Periodicals, Inc.

## Abstract A microstrip bandpass filter with a new type of capacitive‐coupled resonator is presented. The filter is designed to be smaller compared with the same type of parallel‐coupled bandpass filter. The filter is designed for a centre frequency of 2.5 GHz that lies in the S‐band frequency ran

## Abstract We present a novel UMTS diplexer design using the filters of antiparallel‐coupled lines structure loaded with a stepped impedance microstrip resonator. The diplexer is composed of two filters. And a microstrip line of quarter‐wavelength is used to links each filter to the common port. T
