Microstrip patch antenna with a circular complementary split ring resonator

Abstract

A novel dual-band microstrip patch antenna embedded with two circular complementary split ring resonators (CSRR) for operating in S- band (2-4GHz) as well as C-band (4-8GHz) is proposed. An effective dual-band microstrip patch antenna can be designed by etching two CSRRs in a conventional patch antenna. The proposed antenna operates at 3.4GHz as well as 4.3GHz. It is advantageous for designing a dual-band microstrip antenna with miniaturized size for satellite applications. At both operating frequencies, the antenna exhibits better performance. The CSRRs embedded on the patch antenna helps in miniaturization of the patch antenna. Up to 70% of the size reduction is achieved when compared to the basic patch antenna which operates at 3.4GHz.
