Abstract

A novel broadband bandpass filter with multiple resonant modes based on parallel‐coupled microstrip line is proposed. The required cutoff frequency and out‐of‐band performance are achieved by placing L‐shaped capacitive cross‐coupling open stubs at the middle resonator with appropriate dimensions. A compact broadband bandpass filter of dimensions 18 × 29 mm2 is fabricated and tested for performance confirmation. The proposed filter demonstrates a wide bandwidth (from 3 to 7 GHz), as well as excellent out‐of‐band performance with more than 25‐dB rejection up to more than 12 GHz and sharp upper cutoff frequency due to the proper location of two transmission zeros.
