Analysis and experimental validation of a triaxial antenna for microwave tumor ablation

Year: 2004

Type: conference-paper

Abstract: We apply a new triaxial antenna for microwave ablation procedures. The antenna consists of a coaxial monopole inserted through an 18-gauge biopsy needle positioned one quarter-wavelength from the antenna base. The biopsy needle creates a triaxial structure, which enhances return loss by more than 10 dB, thus limiting return currents along the feed line. Numerical simulations are used to optimize the antenna design. Numerical and ex-vivo experimental results are presented to quantify the field distribution, heating pattern and return loss of the antenna.
