A breast model has been proposed in this paper. The model is designed on CST Microwave studio. The outer layer is skin, then fat layer and then breast tissue layer is made of different dielectric constant materials. The tumor is taken as a sphere which is placed inside the breast at different positions for detection purpose. A novel antenna to detect breast cancer tumor is also proposed in this paper. The UWB antenna is designed in the frequency range 3.3-10.6 GHz. The antenna shows a return loss S11 less than -10 dB for the UWB frequency range and a maximum gain of 3.49 dB in this range. The designed UWB antennas can be placed on both sides of breast model such that the signal scattered by the breast tumor can be detected by the receiving antenna. The overall size of antenna is 20X30 mm2 and designed on FR4 substrate.
