Abstract

The effect of multilayer, 2-D photonic band gap substrate on the performance of rectangular microstrip patch antenna at THz frequency is simulated. The radiation efficiency, gain and directivity for the proposed antennas are 93.28%, 10.46 dB and 10.76 dBi, respectively at 875 GHz. The 10 dB impedance bandwidth of the antenna is 36.67%, which is ultra-wide bandwidth. The simulation has been performed by commercially available CST Microwave Studio simulator, which is based on the finite difference time domain technique (FDTD).
