Frequency Reconfigurable Micro-strip Patch Antenna for Wideband Applications

A frequency reconfigurable microstrip patch antenna is presented in this paper. The antenna is designed to achieve the reconfigurabilty within the band i.e. wideband(X-band). The proposed antenna is multipart eight armed star shape frequency reconfigurable antenna designed to cover the frequency band from 7.5 GHz to 14 GHz. The antenna exhibits the property of change in frequency which results in change in return loss characteristics depending upon the configuration request. The frequency reconfiguration capability of antenna is achieved with the help of metal strip line which acts as a switch to reconfigure the antenna.
