A simple design of low cost planar circular monopole antenna for ultra-wideband (UWB) communication system applications is presented. The proposed antenna consists of a planar circular radiating patch fed by a simple 50Ω microstripline feed. The antenna is etched on a substrate area of 50 × 3.8 mm2.By properly adjusting the physical parameters of the antenna a wide impedance bandwidth can be achieved from 2 to 12.63 GHz which is 145%. The parametric analysis based on obtained results of the proposed antenna is discussed and presented
