Abstract:

Microwave ablation (MWA) is relatively safe and efficient treatment method for the patients suffering with liver tumors. The antenna is integral part of the MWA setup. The optimized design of antenna play important role in investigating the effectiveness of MWA therapy. Tapered Cap Floating Sleeve Antenna was simulated, designed and optimized to treat the malignant liver tumors. The strength of tapered cap floating sleeve facilitates the antenna to be inserted into the liver tissue without requiring any insertion device. The tapered cap length was optimized at 5 mm having base diameter of .25 mm at an angle of 280 where the antenna resonated at the operating frequency of 2.45 GHz. Tapered cap floating sleeve antenna is able to generate perfectly spherical ablation zone at the tip without increasing the radial dimensions of the antenna. The SAR patterns were obtained at different insertion depth and it has been observed that the SAR distributions were unaffected by the insertion depth.
