Abstract: In this paper, a novel design for miniaturization of microstrip patch antenna with multiband operation of microstrip antenna is proposed. The technique is based on etching out of Complimentary Split-Ring Resonator (CSRR) on the radiating edge of the patch antenna. Numerical simulations are presented for a patch antenna with and without CSRRs by using IE3D simulation software and measured practically. The measured results shows that antenna with CSRRs on the radiating edge of the patch antenna is resonating at four different frequency points i.e., 4.96GHz, 6.05GHz, 8.62GHz and 11.25GHz., whereas, antenna without CSRR i.e., conventional microstrip antenna is resonating at 5.98GHz. The size reduction of 16.92% is achieved and the antenna gives the overall bandwidth of 17.88%. These antennas find application in Wireless Communications.
