Abstract : This article presents the design and implementation of an 88 × 85 mm reconfigurable filtering bow-tie antenna with four operating states. Two PIN diodes are deployed to reconfigure the transmission zeros to realize ultra-wide band (UWB), 3.5/5.5 GHz with independent switching. This switching prevents the interference of the primary user into the secondary user thereby making the filtenna suitable for cognitive radio applications. The proposed filtenna consists of a UWB bow-tie antenna integrated with a band-pass filter with reconfigurable property enabled using two PIN diodes. The prototype-filtering antenna is fabricated and the simulated results are validated using measurements. The presented results show that the antenna exhibits good impedance and radiation characteristics.
