The Improvement of Characteristics of The Applicator Using Semi-rigid Coaxial Cable Antenna for RFA
반강체 동축케이블 안테나를 이용한 RFA용 어플리케이터의 특성 개선
Abstract
Radiofrequency ablation (RFA) as one of the microwave hyperthermia is becoming the treatment of choice for small but inoperable tumors of the liver. In this paper, we designed the applicator composed of semi-rigid coaxial cable antenna with a ring slot for RFA. To optimize the maximum output of radiation with omni direction at 2450 ㎒, we simulated the applicator using Electromagnetic simulation program and analyzed the return loss and the electric field E
