Abstract: A frequency-reconfigurable microstrip patch switchable to slot antenna is proposed. The antenna is capable of frequency switching at nine different frequency bands between 1.98 and 3.59 GHz. The patch is resonating at 3.59 GHz, while the slot produces eight different operating frequencies between 1.98 and 3.41 GHz.

Design and Implementation of Reconfigurable Antenna redistribute the antenna currents. Radio frequency micro-electromechanical systems (RF-MEMS) have been proposed for integration into reconfigurable antennas since 1998 [5]. Many designs have resorted to RF MEMS to reconfigure their performance. RF MEMS based reconfigurable antennas rely on the mechanical movement of these switches to achieve
