Small Loop Shape Antenna for Generating a Localized Heating Region

Microwave energy devices can coagulate biological tissues without generating surgical smoke. Therefore, we proposed the double-loop shape antenna for miniaturization and generating a localized heating region to adapt microwave energy device for robotic surgery. In order to evaluate the heating characteristics, numerical analysis and heating experiment were calculated. As a result, it is confirmed that the double-loop shape antenna with 10 mm rod can generate uniform heating region.
