A proximity feed ultra-wide band (UWB) patch antenna with four notched bands is presented. The proposed antenna introduces UWB performance in the frequency range of 1.9 GHz to 10.3 GHz with omnidirectional radiation pattern. Slots etching techniques are utilized to provide four notchedbands at frequencies of 2.3, 2.8, 3.5, and 5.5 GHz to avoid the interference with the wireless networks ... Read more
