A compact ultra-wideband (UWB) antenna with tunable band notched characteristics is proposed. Varactor loaded, two via edge located (TVEL) and fractal electromagnetic band gap (EBG) structures are designed for tunable band-notched characteristics. The varactor diode near the TVEL EBG tunes the band notch frequency for WiMAX (2.8-4.0 GHz) band, while another varactor near fractal EBG structure tunes band-notch frequency for WLAN (4.7-6.2 GHz) band. The varactors are independently controlled to achieve WiMAX and WLAN notched band. Notch frequencies can be continuously tuned by varying the bias voltage across the varactors. The proposed antenna of 24×24 mm2 dimensions is fabricated on an FR4 substrate. A good agreement between simulation and measurement results is obtained. A continuous band notch tuning from 2.8 to 4.0 GHz and 4.7 to 6.2 GHz is obtained using varactor diodes having capacitance in a range of 0.497-2.35 pF.
