Abstract : As the wireless devices are becoming smaller and smaller day by day, the size reduced antennas required on such devices are in huge demand. A lot of research is going on for smaller and size reduced antennas like using quasi-self complimentary structure fractals and so on. Here we have designed a bandwidth enhanced antenna by notching the lower edges of the Rectangular Patch antenna. We have proposed a compact size frequency reconfigurable of 17 mm x 17 mm antenna. This antenna acts as a sensing antenna at one particular switch configuration which covers the entire UWB band. While it is reconfigurable into subsequent sub-bands at different switch configurations, we have achieved reconfiguration into three subsequent bands. The material used is FR-4 which has a di-electric constant of 4.4 and thickness of 1.6mm. The simulations are performed on HFSS 13.0. Keywords- Reconfigurable Antenna, Cognitive Radio, UWB Antenna, Compact Size Antenna.
