Analysis and Performance Evaluation of Microstrip Patch Antenna for X- Band Applications

Meenakshi Dular, Ira Joshi

In this paper, a design of Microstrip Patch Antenna for X- Band applications is proposed. The input impedance of the antenna is 50Ω. The Proposed antenna resonates at 10.62 GHz having return loss value of -20.36dB. The total bandwidth of the proposed patch antenna is1.88GHz. The antenna is fed by a micro strip feed. The Rogers RT/ Duroid 5880 (tm) is used as a substrate, and antenna dimensions of 30mm x 25mm in X and Y directions and having a thickness of 1.6mm. The results are simulated by using Ansoft HFSS software. Also gain, directivity and bandwidth of the proposed antenna are studied.
