Designing of Band Notched Print Antenna for Ultra Wideband Applications

In this paper a new ultra wideband (UWB) antenna is proposed with band notch characteristics to avoid interference with WLAN//HIPERLAN in 5.15 GHz – 5.85 GHz band. In proposed antenna a wide impedance bandwidth is achieved (3.15 GHz – 15.7 GHz) to fulfill requirements of UWB for future applications? The proposed antenna is investigated with partial ground plane. It has a simple geometry and by cutting three slots band rejection characteristic of proposed antenna are achieved. The measured S11 is well below 10 dB & measured radiation patterns are near omnidirectional.
