Abstract

A new bandstop‐coupled line filter using spurline structures has been presented in this work. The new bandstop filter enhances the rejection bandwidth of bandstop coupled line filters in a 50%. To demonstrate the idea, classical bandstop‐coupled line filters with and without simple spurlines structure were designed using Rogers material, and their frequency response were compared. Simulations performed with momentum agree with experimental results, demonstrating the usefulness of spurlines structures in the enhancement of the bandwidth of coupled line filters. © 2011 Wiley Periodicals, Inc.

## Abstract In this paper, a microstrip parallel‐coupled bandpass filter based on electromagnetic bandgap (EBG) structures to achieve spurious suppression is presented. The EBG loops of the middle layer add an extra stopband‐rejection mode to the 2^nd^ and 3^rd^ harmonics of the filter with attenua
