Normalized SAR map of the dual-slot coaxial antenna for G1 = 1 mm, L = 8 mm, and G2 = 4 mm at 2.45 GHz in normal liver tissue demonstrates that heating is relatively confined to the distal end with the most optimal design. Slots are located at 63 and 72 mm. Isocontours are provided from 0 dB to −60 dB below the peak SAR around the tip of the antenna.
