We present design results of two cases of Ultra Wide Band (UWB) quasi circular patch antennas, one with coplanar feeding (CPW) and the other one with microstrip feeding. Both antennas are an evolution from a circular patch structure softening the edges to improve the antenna performance, agreeing with the theory proposed Kraus. After the evolution there were improvements concerning reflection coefficient and number of resonant frequencies throughout the operating bandwidth. The operational frequency range is from 500 MHz to 15GHz using a design frequency of 4.5 GHz. The antenna feeding impedance is proposed to be 50ohms. The antennas with the best simulation response are constructed to test the practical performance of experiment.
