Comparison of Two Small Circularly Polarized Antennas for Focused Microwave Hyperthermia

Focused microwave hyperthermia is an attractive treatment technique for breast cancer owing to its high accuracy and efficiency. It requires an antenna array to radiate microwave fields into a breast and iteratively focuses the fields at a breast tumor by optimizing excitation phases and amplitudes of the array. Only linearly polarized antenna elements have been applied for the focused microwave hyperthermia. This work investigates the feasibility of employing circularly polarized antennas for the purpose of focused microwave hyperthermia. Two kinds of circularly polarized antennas are applied and their dimensions are miniaturized to enable arrangement of more antennas around a human breast. Simulation results show that both the tested antennas can obtain microwave field distributions well focused at the tumor in a breast model. Therefore, circularly polarized antennas are suitable for focused microwave hyperthermia.
