Polyimide Substrate based Compact Antenna for Terahertz Wireless Communication Applications

Abstract

This work proposes a square shaped compact patch antenna with microstrip feed line, supporting the terahertz (THz) communication applications. The geometry proposed in this work is realized using polyimide substrate, whereas the conducting material used for the patch is Gold metal. The presented antenna with overall substrate dimensions of 300 x 300 µm2 offers wide bandwidth ranging from 580 - 660 GHz and high gain of 7.155 dB. The simulation results demonstrates good radiation behavior of the antenna. Thus, it is ascertained that the suggested antenna is a promising contender for THz wireless communication systems.
