Microwave Ablation Antenna with the ablation pattern being a figure-of-eight

Abstract

In this paper, we report a multi coaxial-slot antenna for microwave ablation (MWA). This device is based on coaxial multi slot radiation. This coaxial antenna was slotted two aperture to form a figure-of-eight MWA area. The Microwave Ablation Antenna works at 2.45GHz and also has a good impedance matching. This kind of Microwave Ablation Antenna can solve the specific shape of the tumor and to realize a large ablation pattern, meanwhile our design has lesser damage to body (for the outer radius of the coaxial-slot antenna is less than 4mm).
