In this paper, the effects of 2-D photonic crystal substrate on the performance of a rectangular microstrip patch antenna at terahertz frequency (0.4-0.8THz) has been investigated. The photonic substrate has been used to enhance the gain and radiation efficiency of the proposed antenna. The gain and radiation efficiency of this antenna at 600 GHz is about 13dB and 83.02%, respectively. This antenna...
In this paper, a dielectric slab with the periodic implantation of the air gap in the host passive substrate material has been analyzed. The effective permittivity of the photonic crystal with host material PTFE at 600 GHz has been extracted with the help of robust method to retrieve the constitutive effective parameters of the metamaterials. Based on the extracted effective permittivity, a rectangular...
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...
