✦ Synopsis

Abstract

Microwave filters in microstrip technology have been designed by taking advantage of metal patterning of the front and back‐side planes. It is shown that such an approach with drilled holes in the ground plane for the high impedance sections permits one to alleviate some of the drawbacks associated with uniplanar impedance modulated filters with high geometric aspect ratios. Prototypes for the S and C‐bands were fabricated by conventional low‐cost printed circuit techniques and show improved performances in terms of rejection and bandwidth. © 2002 Wiley Periodicals, Inc.

## Abstract We report first on an experimental analysis of photonic bandgap microstrip‐type filters at microwave frequencies. The frequency‐selective structure is achieved via ground‐plane patterning. The influence of a shielding is addressed in particular. Then, we theoretically analyze the possib
