Compact dual broadband ladder PCML filter with rectangular resonators

Marimuthu, J. and Esa, M. (2009) Compact dual broadband ladder PCML filter with rectangular resonators. In: 26th Progress In Electromagnetics Research Symposium (PIERS) 2009, 18 - 21 August 2009, Moscow, Russia.

Abstract

A simple configuration of dual broadband parallel coupled microstrip line (PCML) bandpass filter operating at 2.65 GHz and 7.85 GHz frequency bands with wide stopband design is presented. The proposed filter is composed of a pair of high coupling factor PCML structure, low impedance middle resonator and feeding network. Overall the simulated and measured results of insertion and return loss show good agreement with BW= 1. 8 GHz (85%),| S11|<− 12 dB,| S21|>− 0. 3 dB at 2.65 GHz and BW= 1. 8 GHz (25%),| S11|<− 10 dB,| S21|− 0. 5 dB at 7.85 GHz with overall stopband of 5.2 GHz.
