Hyperthermia for Breast Cancer Treatment Using Slotted Circular Patch Antenna

Abstract

The primary intent of this paper is to investigate the potential of using a slotted circular patch antenna at 2.45 GHz for breast tumor hyperthermia treatment. A cancer treatment model consisting of a microstrip patch antenna and breast phantom comprising tumor is designed and simulated in CST Studio Suite 2018. The radiation properties of the proposed antenna attain 3 dB beam width of 74.1˚ and 70.5˚ for the E-Plane and the H-plane, respectively. The breast phantom is exposed to the designed antenna radiation for 10 minutes, leading to raise the breast phantom temperature by 8.5˚C and 11.4˚C once the antenna pumped power is 1.5 and 2 watt, respectively. By considering 10 minutes as an exposure time, the breast temperature as a function of the applied antenna power is studied and compared with previous published results.
