A compact microstrip antenna for terahertz applications is proposed and its characteristic parameters are analyzed by utilizing several conducting dielectric materials. The consists of a modified E-shaped patch slot loaded T-shaped ground plane. THz structure designed on 45 µm thick Rogers RT/Duroid 6010™ substrate with grapheme as material. performance using High Frequency Structure Simulator the optimized dimension 130 × 100 µm2. graphene based exhibits wide impedance bandwidth (IBW) 450 GHz from 0.57 to 1.02THz fractional (FBW) 56.60%. shows significant improvements in FBW ratio (BDR) due incorporation rectangular suggested offers maximum reflection coefficient (S11) −19.49 dB, adequate VSWR (<2) over operating band, peak gain 3.47dBi, radiation efficiency 92% 1206.05. Furthermore, effects different materials (Rogers 6010, Polyamide, Sio2, Arlon CE 1000) (copper, silver, gold) investigated discussed. suitable ultra – speed short distance communication, medical, imaging sensing region.
