A Switchable Filtering Antenna Integrated with U-Shaped Resonators for Bluetooth, WLAN & UWB Applications

In this paper, A Switchable Filtering Antenna Integrated With U-Shaped Resonators for Bluetooth, WLAN & UWB Applications is presented. To achieve the operation, a rectangular defect on ground plane and square slots are etched patch. The selectivity of frequency achieved by integrating Hairpin filter. Three switches connected at corners filter to re-configurability. total eight Boolean combinations possible controlling ON OFF these switches. This filtering antenna acts as band pass picks distinct bands within frequency. It can be used wireless applications such Long-Distance Radio Communication, Aviation Services, WLAN, C-band satellite communication, Wi-MAX, mobile sub-band, radar communications, space communications. addition, two inverted U- shaped resonators differing lengths engraved microstrip patch operate Bluetooth with frequencies ranging from 2.4 2.458GHz. maximum gain obtained out all operating 4.82dBi 9.5GHz. proposed simulated using 3D-Simulation tool CST MWS. performance designed estimated parameters like return loss, VSWR, Far-field Gain characteristics.
