In recent few decades, various types of medical applications of microwaves have widely been investigated and reported. The authors have been studying the thin coaxial antennas for minimally invasive microwave thermal therapy, particularly, microwave coagulation therapy (MCT). The MCT is considered to be a very effective treatment for small size tumor. However, there are some problems to be improved for conventional MCT antennas. Particularly, there is a problem that length of the coagulated region becomes long and uncontrollable in the antenna insertion direction. In this paper, we improve the structure of the antenna to generate a localized heating region only around the tip of the antenna by using computer simulation.
