Abstract

Using metamaterial based 3×4 array split ring resonators on to a stepped rectangular patch antenna with defective ground plane is proposed for energy harvesting at downlink radio frequency range of GSM 1800 band. The study is focused on investigation for improvement in the performance of antenna over the conventional patch antenna by shaping the meta-material structure of superstrate layer. The results showed an improvement of 17.25% (109MHz) impedance bandwidth and gain of 61.16% (1.907). Also the effects of position, the distance of superstrate layer (air gap) and the dimensions of antenna are analysed. The results of the simulation without and with metamaterial structure on the performance of the antenna were discussed in this article.
