Abstract: This paper presents an evaluation of frequency reconfigurable patch antennas for X-band, using PIN diode as a switch. A pin diode is incorporated in the slot etched on rectangular patch antenna. The frequency band selectivity can be achieved by controlling the state of switch inserted in the antenna. We are using IE3D simulation software for designing and analysis. We have discussed and analyzed the performance of unslotted Rectangular Microstrip patch antenna and slotted rectangular patch antenna with PIN diode in ON and OFF states.

Keywords: Microstrip Antenna, Return Loss, Radiation pattern, IE3D.
