The terahertz communication is highly attractive for high-speed data communication due to its large bandwidth. In this work, Frequency Selective Surfaces (FSS) -based patch antenna was designed for improving gain, bandwidth and directivity. Initially, square loop (SL) band stop FSS unit element was designed with a frequency range of 1.5 THz and the parameters are extracted by using MATLAB. Then the proposed FSS elements are converted into 9x9 square loop structures and embedded with the bottom of the patch. The simulation results show that the proposed FSS substrate patch antenna bandwidth is improved from 1230 GHz to 2260 GHz in the desired frequency band. The gain and directivity of an antenna were also improved by 3.73dBi. From the simulation results, it is observed that the proposed dual-layer FSS substrate-based patch antenna is suitable for 6G wireless networks..
