In this paper, a printed Ultra Wide Band (UWB) antenna of small size with variable frequency band-notched properties is presented. Finite element based HFSS software is used to simulate the proposed antenna and then fabricated. The parameters of fabricated antenna are measured with E5071C vector network analyser. The measured and simulated results are in good agreement. A stepped radiating patch is printed on one side and stepped ground plane on the other side of FR- 4 substrate to increase the bandwidth from 4.3 GHz to 11.28 GHz. Introduction of two protruding strips having a length of λ/2 in rectangular slot results to get frequency notch characteristics in WLAN (5.15–5.85 GHz) band. The effects of length and thickness of individual protruding strips on band notch characteristics are examined. By varying either the length or the thickness of protruding strips incorporated in the rectangular slot, we can control the band notch frequency and its band width. The presented antenna has a small size of 12 x 18 x 1.6 mm3and reveals a steady gain throughout the UWB except at notched band of 4.9 GHz 6.1 GHz. The radiation pattern in the E-plane and H-plane is like a figure of eight.Keywords
