Design a Uplink-Downlink Reconfigurable Patch Antenna for Modern Space Application

Naman Mehrotra | Dr. K. M. Singh | Shashibhushan Sharma

Abstract: In this paper, a modified elliptical reconfigurable patch antenna with stripline feed has been analyzed and simulated for the Modern satellite communication Applications. The overall size of the antenna is 60mm 60 mm 1.59 mm. The antenna has been operated on two different resonant frequency of 3.93 GHz (downlink) and 6.15 GHz (uplink) for satellite and application band on the basis of switching conditions. The simulated gain of antenna in the obtained frequency range is closed to 4.7 dBi and 3.6 dBi for OFF and ON conditions respectively. Maximum radiations are directed normal to patch geometry and shape of patterns is somewhat similar to a isotropic radiation pattern [4] as a dumble shape in the upper hemisphere. This reconfigurable patch antenna has been designed specifically for the application of satellite communication systems. The proposed antenna has been simulated by applying CST Microwave Studio Software.
