Semi-rigid antenna working in ISM 2.4GHz used in microwave ablation

Abstract

The paper presents the concept and design of an interstitial microwave ablation directional antenna which can be used for biomedical applications. The antenna works in the microwave band ISM2.4GHz. The work focused on optimizing the size of the radiating element to obtain an impedance matching less than -14dB (VSWR <1.5) and directional radiation pattern.
