A microstrip patch antenna with a 2D multiperiod electromagnetic band gap (EBG) sandwiched between the patch and the ground plane is proposed and studied in this paper. The proposed models are assessed using finite‐difference time‐domain (FDTD) simulations and experimental measurements. The simulated and measured results show that, with the sandwiched multiperiod EBG structure, the microstrip patch antenna can achieve wider impedance bandwidth and higher gain than the sandwiched single‐period EBG structure. © 2005 Wiley Periodicals, Inc.
