Abstract: This article presents a novel reconfigurable antenna in which both frequency of the antenna and its pattern are reconfigured. A T- shaped rectangular patch which is attached by two longitudinal slits is present in the antena. The slits have been related to a pin diode to obtain the required frequency bands and pattern reconfiguration. The antenna is designed with 70*70 substrate dimension having FR4 as a material and designed using HFSS 18 The frequency reconfiguration can be seen in between at 4.5GHz /5.8GHz/11.4GHz and 13.6GHz which are used for the WLAN and vehicular communications. Along with that a pattern reconfiguration of about -150 ,150 ,300 degrees tilt in the angle is observed in the radiation patterns at the same bands. Prototype antenna is fabricated and tested in the real time electromagnetic environment and results measured are shown like that of the simulated results in HFSS.
