Abstract

In this paper, a microstrip patch antenna for X band application is proposed and designed. The proposed antenna is designed with slots in order to achieve the narrow bandwidth. The FR4 substrate with the thickness of 0.8mm is employed in this design. The proposed antenna resonates at 11.2GHz with the return loss and voltage standing wave ratio of -29.5288dB and 1.005, respectively. The dimension of the antenna is 10mm and 7.7mm. Slots are taken in this design in order to enhance the bandwidth. The slots are used in the shape of split ring resonator with the radius of 0.85mm and 1.25mm for inner ring and outer ring, respectively. The major advantage of the proposed antenna is its compactness and bandwidth.
