Modeling and optimizing Ultra Wideband antennas for microwave breast cancer detection

In this paper, two compact Ultra Wideband (UWB) antennas have been proposed to be in touch with skin for microwave breast cancer detection. The UWB techniques allow for a good shape-identification and allow sensing of dielectric properties differences among tissue types over a very wide frequency band. The UWB antennas are designed and analyzed using CST simulation tool in transient mode to verify antenna parameters improvements. The simulation results indicated the improvement of the antenna response by properly selecting antenna dimensions and antenna shape.
