Design of Wearable UWB Microstrip Patch Antenna for Breast Cancer Tumor Detection

Abstract

A novel approach to detect breast cancer tumor is proposed in this paper. The UWB antennas are designed in the frequency range 3.3-10.6 GHz. The antennas show 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 such that the signal scattered by the breast tumor can be detected by the receiving antenna. A breast model is designed which is simulated with UWB antenna on both sides, the variation of E field, H field and current density is shown with and without tumor for various position and size of the tumor, the difference between these values will detect the presence of tumor. The SAR is also simulated for different frequencies in UWB range with variation in size and position of the tumor. The simulated results can be observed and the presence of tumor can be detected.
