摘要：
In this paper, a compact Ultra-Wideband (UWB) slot antenna with band-notched performance is presented. In order to increase the impedance bandwidth of an ordinary slot antenna, we use a pair of S-shaped slots in the ground plane that with this structure, a new resonance at the higher frequencies can be achieved and a wide usable fractional bandwidth of more than 130% is provided. Additionally, by using a protruded E-shaped strip inside the square-ring radiating patch, a frequency band-notched function has been obtained. The designed antenna has a small size of 20x20 mm(2) while showing the radiation performance in the frequency band of 3.13 to over 14.3 GHz, with a band rejection performance in the frequency band of 5 to 6 GHz. Simulated and experimental results obtained for this antenna show that it exhibits good radiation behavior within the UWB frequency range.
