Investigations on Indium Tin Oxide Based Optically Transparent Terahertz E-shaped Patch Antenna
An optically transparent microstrip patch antenna is designed and its radiation characteristics are analyzed in 706 - 794 GHz band. Terahertz communication systems offer advantages such as broad bandwidth, low transmit power, secured wireless communication and compactness. It has applications in various fields like hidden object detection, imaging and sensing. In the proposed antenna, transparent conducting indium tin oxide thin film is used as a radiating patch and a ground plane material. The entire antenna structure is optically transparent in the visible spectrum region. The proposed antenna is simulated using Ansoft – HFSS, a finite element method (FEM) based electromagnetic solver.
