Abstract
A novel reconfigurable rectangular microstrip patch antenna (RMPA) is presented for S-band applications which can be switchable at two different radiation patterns. The designed antenna consists of eight parasitic elements which are connected to the rectangular patch using eight radio frequency micro-electromechanical system (RF MEMS) switches, and by controlling the switches, antenna has omnidirectional radiation pattern in OFF mode and monopole-like radiation pattern in ON mode. In OFF mode, the designed antenna resonates at 2.39 GHz in industrial, scientific and medical (ISM) band, and in ON mode, it resonates at 2.66 and 3.5 GHz. In both the modes, the return loss S11 < −10 dB and gain is more than 6 dBi. The antenna is simulated using CST MW studio and the simulated results are presented.
