Targeted Radiation Dipole Antenna using 3D Numerical Simulation in Microwave Ablation

Microwave ablation technology is being utilised in several medical applications for ablation therapy and other applications. Microwave energy generates fast and high temperatures sufficient and capable to produce coagulation necrosis. Theoretical models by numerical simulation of microwave ablation is a distinct step in the implementation of system design, as well as in the results analysis before the ablation procedure. Furthermore, these models play a role in design the microwave antennas. Classic microwave ablation antenna around its radiating section applies electromagnetic field in tumors without worry about near neural structures. This paper presents the temperature distributions of targeted radiation dipole antenna model with active and non-active sides for microwave ablation at 2.45GHz at different powers and ablation times. Temperature maps and SAR distributions around the radiating section show in two sides.
