Antenna Phase Optimization for Breast Cancer Hyperthermia Applications

Abstract

In this work, the phases of dipole antennas were optimized to focus the electromagnetic energy to a target tissue located in a simplified breast medium using an analytical approach. To perform the optimization, two dimensional model was considered. To simplify the breast model, two cylinders with fat and malignant tumor dielectric properties were considered. The dipole antennas are placed around the phantom material with 45° degrees angular spacing. The optimization was performed by selecting the phase values that wills allow focusing the electromagnetic field to target area. A Yagi-Uda antenna designed to operate from 1 to 4 GHz will be used to test the optimized phase values in the simulations and experiments.
