Abstract
The motivation behind this study is specifying the proper arrangement of periodic air slots within the multi-slot coaxial antenna with 50-Ω feeding load operating at 2.45 GHz to provide the conformal microwave thermotherapy. The desired temperature profile of the liver tissue was numerically evaluated for coupled electromagnetic and thermal problems by the finite element method. Considering the growing number of radiating apertures within the thin microwave needle applicator requires some unique optimization approach based on the S11-parameter characteristics to guarantee the best antenna–tissue impedance matching. Moreover, the proposed multi-step iterative numerical procedure allows effective modelling of optimal placement of the periodic slots of microwave antenna, required limit levels of the antenna power input and thus conformal cancer treatment for both interstitial microwave hyperthermia and thermal ablation.
