Enhanced gain dual band patch antenna based on complementary rectangular split‐ring resonators

A simple and successful dual band patch vertical polarized 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. Furthermore, a miniaturization of the conventional rectangular patch antenna and an enhancement of the complementary split ring resonator resonance gain are achieved. The dual band antenna design has been made feasible due to the quasi-static resonance property of the complementary split ring resonators. The simulated results are compared with measured data and good agreement is reported. © 2011 Wiley Periodicals, Inc.
