            Abstract : 
An UWB Vivaldi Antenna structure is presented and analyzed for tumor detection of brain cancer. Various antenna configurations are considered in this analysis. The radiation is investigated inside a human head phantom with a tumor model. The antenna is designed with FR-4 substrate, and is tested when immersed in background of relative permittivity 40 to achieve good matching with the head tissue. Results show that good performance is obtained for the design size of 329.25×153×1.6 mm, and the antenna is found to operate in the range 100 Mhz to 1.4 GHz.
