A compact water loaded choke configurations for intracavitary microwave hyperthermia
This paper presents a compact water-loaded coaxial balun configurations for targeted heat delivery for intracavitary hyperthermia treatment of cancer. Balun configurations of choke were analyzed using a 3$\lambda$/8 monopole at 915 MHz. The surface current density and volume loss density characteristics were used to evaluate balun efficiency and were compared with a conventional monopole without balun. The antenna performance with and without the balun configurations was numerically assessed and compared in terms of specific absorption rate (SAR) and input power reflection coefficient. The numerical designs were experimentally validated in muscle mimicking liquid phantoms.
