Abstract :
A microstrip patch antenna on a two-dimensional multi-period electromagnetic bandgap (EBG) structure, embedded between the patch and the ground plane, is proposed and studied in this paper. The impedance bandwidth, radiation pattern and gain of the antennas are assessed using finite-difference time-domain (FDTD) simulations and experimental measurements. The simulated and measured results show that the microstrip patch antenna on the sandwiched multiperiod EBG structure can achieve wider impedance bandwidth and higher gain compared to the one on a single period EBG structure. At the same time, the size of the substrate can be reduced substantially.
