Abstract
The focus of this project is to carry out an accurate simulation study of a 3- element array of rectangle horn antennas forming a focused near field beam. This study has useful application for clinical hyperthermia which is the therapeutic treatment of tumors in the body by heating caused by focused RF or microwave radiation. This principle of treatment is proved to be very useful for cancer treatment usually in conjunction with traditional radiation or chemotherapy, and can even double the tumor response rate as compared to radiation alone.. The 3-element array set up consists of a central focusing element and two surrounding directing elements. The focusing element can be axially adjusted and surrounding elements are fixed to focus the beam of a required point, which is necessary in hyperthermia treatment. In this project the simulation results were obtained from ANSOFT HFSS simulations.
