Abstract

A direct circuit replacement method using interdigital low‐pass structure directly replaced all open stubs of odd‐order open‐stub low‐pass filter to achieve sharp skirt response. The characteristics of the interdigital structure are analyzed by lumped element equivalent circuits and investigated by full‐wave electromagnetic simulator, IE3D. These simulated results were then applied as a guideline for the replacement. Two open‐stub low‐pass filters were designed by this method to enhance the skirt response near 3‐dB cutoff frequency. The measured results show very good improvement on skirt response and the rejection level in stop band. © 2007 Wiley Periodicals, Inc.

## Abstract This paper discusses a method used to design a planar bandpass filter in the Ku‐band frequency range for a given satellite application. In order to fit a hardened specification, a dual‐behavior‐resonator (DBR)‐based filter topology is employed. In association with this topology, we prop
