Dual band patch antenna based on complementary rectangular split-ring resonators

Abstract

A simple and successful dual band patch rectangular antenna design is presented. The dual band antenna is designed etching a complementary rectangular split ring resonator in the patch of a conventional rectangular patch antenna, achieving a miniaturization of the conventional antenna. The dual band antenna design has been made feasible due to the quasi-static resonance property of the complementary split ring resonators. Simulated results are compared with measured data and good agreement is reported.
