Abstract :
A simple design method for an ultra wideband planar monopole antenna is presented. The antenna is to be used in a microwave imaging system for medical applications. The designed antenna has a compact size, with dimension of 28 mm by 28 mm. The measured 10 dB return loss bandwidth of this antenna element is from 3.2 GHz to more than 15 GHz. Its radiation efficiency is higher than 90% over the whole 10 dB return loss bandwidth. The measured time domain response of the antenna indicates the capability of the designed antenna to support distortionless pulse transmission with a high fidelity factor for any angle of orientation.
