A helical microwave antenna has been designed to improve heat deposition by interstitial applicators used for clinical hyperthermia. Iso-specific-absorption-rate (SAR) curves of the helical antenna as well as a conventional monopole antenna were measured and compared in both muscle and brain tissue phantoms. The heating pattern of the helical antenna is more uniform along the length of the antenna which has important implications for multiarray implant configurations.
