MWA applied to the same tumor and the same condition by three different antennas (λ = 5, f = 2.45 GHz, P = 70W). By using a single slot antenna, around 76% of the tumor is ablated, but the ablation zone is expanded to the surrounding healthy tissue(A). In the case of using a double slot antenna, the ablation zone could be further adjusted into the tumor area by optimizing slot to slot distance (B and C).
