A NOVEL DUAL-BAND PATCH ANTENNA WITH COMPLEMENTARY SPLIT RING RESONATORS EMBEDDED IN THE GROUND PLANE

Abstract

In this paper, a novel design of dual-band microstrip antenna with complementary split ring resonators (CSRRs) is presented. A simple and successful dual-band antenna can be realized by etching three CSRRs in the ground plane of a conventional patch antenna. The proposed antenna shows good performances at both resonant frequencies. The CSRRs embedded in the ground plane make a major contribution to the flrst operating band, but has minor efiect on the second operating band. It is beneflcial for designing a dual-band antenna as well as a miniaturized antenna ∞exibly. The simulation results are analyzed and compared with measured results in a good agreement.
