A small size and low profile microstrip fed frequency notched planar monopole ultra wideband (UWB) antenna with an arc shaped slot etched on a circular disk is proposed. The effect of different dimensions of the slotted arc are analyzed and optimized to obtain simultaneously the UWB and the band rejected performance. The return loss from (3.5–23.64 GHz) along with a notched frequency band (5.23–5.8 GHz) and quasi omni‐directional radiation pattern is observed.
