N2 - In an expanding number of worldwide clinical trials, conventional loop, dipóle and square-patch antennas perform as external hyperthermia applicators for the adjunct treatment of cancer cells at superficial depths inside the human body. A smaller patch design in very close proximity with various phantom tissue models produces focused specific absorption rate (SAR) patterns without significant frequency detuning or impedance mismatch. Synthesized treatment conditions for different body phantoms suggest that the SAR profile of the compact antenna is stable for a range of tissue types and topologies. This paper will describe the miniaturisation and tissue coupling design characteristics for the near-field antenna applicator. Performance metrics are indicated with impedance matching, SAR and thermal profiles.
