Bandwidth and gain enhancement of microstrip antenna usingmetamaterials

In this thesis, the design of the ultra-wideband microstrip antenna based on a metamaterial (MTM) array is presented to increase antenna performance by enhancing the bandwidth and gain. The proposed structure consists of an ultra-wideband antenna and a metamaterial array. The design consists of three steps. In the first step, a traditional microstrip antenna of dimensions 36 x 38 mm2 printed on FR4-Epoxy dielectric substrate with 1.58 mm thickness has been presented. In the second step, a partial ground plane technique has been applied on microstrip patch antenna with the transition steps. A UWB antenna has been obtained that is operating between 2.6 GHz and more than 20 GHz. In the third step, two unit cells of MTMs have been added on the microstrip antenna with a partial ground plane in order to increase the gain of the antenna about 3.19 dB.
