Design of Compact UWB antenna for the Detection of Breast Cancer Tumor

Abstract

A coplanar waveguide (CPW) feed metamaterial inspired rectangular antenna is proposed for breast tumor detection here. The antenna is designed on a Roger RT5880 substrate with the size of 26 mm x 31 mm x 0.127 mm. The proposed antenna has a dual band characteristic operating from 2.86 GHz to 9.53 GHz and 14.0 GHz to 14.89 GHz. The proposed antenna has an Ultra-wideband characteristic with the band width of 6.72 GHz in the frequency range 2.86 GHz to 9.53 GHz. The simulated result of the proposed antenna shows a very good performance in terms of impedance matching, gain, radiation pattern. The proposed antenna is implemented with human breast model in order to detect the tumor. The size and location of the tumor varies and the SAR results are presented. The coordinates of the SAR maximum values are used to detect the location of the tumor inside the breast and the result clearly shows that the proposed antenna has very high precision in identifying the tumor inside the breast. The entire simulation is carried out using CST studio EM software.
