description Microwave ablation for liver cancer treatment has been widely performed due to its minimal invasive technique both single and multi probe. Even though, multi antenna ablation system provide a larger destroy area, however effect of phase shift difference between each antenna is still challenge to be investigate for total ablation result. In this research, we propose a preliminary investigate of phase shift effect to a multi antenna system. Two probes array and three probes array was configured as a multi antenna liver ablation system based on each coaxial opened-slot antenna. By using FEM analyze, we present a full 3D simulation results of those multiple antenna system as phase shift between each probe was varied. Total destroy volume is effected significantly when phase shift was differed from 90°, 180° and 270°.
