✦ Synopsis

Abstract

A compact microstrip dual‐mode resonator with slots in the ground plane is presented in this paper. Several methods for coupling between the dual modes are investigated. One of the methods involves using slots in the ground plane in order to enhance the external coupling and to introduce the necessary perturbation to the initially symmetrical structure. The proposed device requires a surface area about 6 times smaller than the area needed for a conventional patch dual‐mode resonator. © 2007 Wiley Periodicals, Inc.
