Abstract

This paper analyzes different parameters for detecting breast Cancer at a curable stage using the software High Frequency Structure Simulator (HFSS). Model basically consists of a microstrip circular patch antenna, breast model and tumor. This model shows that tumor present in the breast can be detected by observing the change in the distribution of volume current density, the electric field and the magnetic field of the breast in the presence of tumor and in the absence of tumor. The proposed antennas fed a microstrip line on the FR4_Epoxy substrate with a size of substrate width 28 mm and substrate length 30 mm, thickness of 0.8 mm and relative dielectric constant of 4.4 with the radius of 7 mm. The antenna that we designed have an operating range from 3.26 GHz to 12.50 GHz which in the entire UWB (3.1-10.6 GHz) with the return loss - 19.15 dB and voltage standing wave ratio 1.21. The proposed model shows that, in the absence of tumor, the maximum current density, electric field and magnetic field of the breast are 1040.4 A/m2 , 260.10 V/m and 3.038 A/m respectively. On the other hand, in the presence of tumor, the maximum current density, electric field and magnetic field of the breast are 1093.1 A/m 2 , 273.29 V/m and 3.09 A/m respectively. These techniques, which are used for breast cancer detection, are competitively easier, safer and low cost.
