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 propose an automated design procedure that combines both circuit and full‐wave simulations. It is based on a statistical sensitivity study performed by DOE analysis. After development of the base filter, the out‐of‐band rejection is improved by using topological modifications in order to favor the occurrence of transmission zeros. © 2004 Wiley Periodicals, Inc.

## Abstract This paper discusses various changes made in classical coupled‐line narrow bandpass filters to somehow improve frequency response. First, the resonator's strip width was broadened to improve the lines' unloaded __Q__ factor. Second, the in/out coupled‐line sections were replaced by tapp
