Abstract

In this letter, we proposed a comparative study of a rectangular Microstrip patch antenna at Terahertz (THz) frequency ranging from 0.6 to 0.8 THz with and without superstrate. First, the simulation was carried to a simple micro-strip antenna, was then added an upper layer (superstrate) by varying the height to improve impedance matching and optimizing the performance of the antenna. The matching bandwidth and the maximum radiation gain obtained are around 22.47 % (10.43 dBi at 0.6929 THz), respectively. The performance of the dielectric resonator antenna is simulated by electromagnetic simulator CST Microwave Studio.
