Design of Truncated Microstrip Square Patch Antenna for Terahertz Communication

Abstract

This paper presents the effect of truncation on each corner of a microstrip square patch that can be utilized for Terahertz (THz) communication. The truncated microstrip patch antenna has a bandwidth of 410 GHz (-10 dB impedance bandwidth from 3.48 THz to 3.90 THz). Moreover, the proposed antenna reveals a minimum reflection coefficient of about -29 dB, maximum gain of 5.01 dBi, directivity 6.06 dBi and a total radiation efficiency of 80.2% at 3.65 THz frequency. The proposed antenna is suitable for future Terahertz communication and imaging.applications.
