Abstract
In this paper, a circular slot microstrip patch antenna is proposed for Tera-Hertz application. The entire structure is developed on a substrate having 4.4 and 0.02 as relative permittivity ∈ r and loss tangent 0.2on FR4 substrate. The total size of the proposed antenna is 40 × 40 μm2. The height of the substrate is 1.6 μm. The proposed antenna has four resonating bands from 2.36 THz to 3.20 THz with the bandwidth of 2.69 THz, 3.92 THz to 5.38 THz with the bandwidth of 4.79, 7.36 THz to 8.70 THz with the bandwidth of 7.95 THz, 12.86 THz to 14.35 THz with the bandwidth of 13.70 THz. The Computer simulation tool an electromagnetic software is used for simulating the entire projected antenna. The simulated results such as return loss, VSWR, surface current, radiation pattern, gain, and directivity are presented. The simulated results show that the presented antenna is the right choice for Tera-Hertz application.
