The present study proposes a dipole filtering antenna with wide-band characteristics for communication. The filtering is achieved by employing parasitic elements and wide-band characteristic is obtained by reshaping the dipole and using specially designed balun structure. One radiation null is optimized at the higher frequency band limit for sharp transition from pass band to stop band via two half-rectangular ring resonators. The antenna operates between 2.6 and 5 GHz and has maximum realized gain of 8.39 dBi. The |S11| is less than -10 dB in the operating frequency band. The simulation results and evolution of the design procedure are presented.
