Abstract
A novel star-shaped microstrip patch antenna for terahertz frequency applications is presented in this research. It does a thorough examination of the antenna’s performance, taking into account important factors as gain, VSWR, directivity, total bandwidth coverage, along with return loss. A $70 \mu \mathrm{~m}$-thick polyimide substrate with a lower dielectric constant of 3.5 is used in the antenna’s design. The connection among the source and patch of the proposed antenna is facilitated by a thin microstrip line. Operating in the frequency range of 0.959 to 1.296 THz, the proposed antenna has a total bandwidth of 0.337 THz, having its resonance frequencies around 0.991,1.106, and 1.210 THz, in that order. It also achieves 9.82 dBi of directivity and an overall gain about 8.50 dB within its frequency range.
