Abstract

An optically transparent and efficient microstrip patch antenna were designed in Meshed configuration and radiation characteristics were calculated in the Terahertz region. The proposed antenna consisted of Graphene, a transparent conducting material used as a radiating patch as well as a ground plane separated by the 15- micron thin polyimide material. A patch of dimension (1.36×0.102) mm was created from which a rectangular array pattern of 7×7 was etched away from the patch layer each with a size of (0.084×0.118) mm. Based on see-through effect and material properties, the proposed structures provide sufficient optical transparency of greater than 97%. The proposed design has yielded an efficiency and gain of 75% and 6dB respectively at 0.675 THz. The proposed antenna is also compared with the conventional antennas operating in a terahertz band. The antenna is simulated by using the computer simulation technology (CST) which is based on the finite element method. This antenna is designed with the objective of enabling its use in space applications to provide optical transparency for the solar cell and making compact devices..
