Different ablative therapies are clinically used to treat liver cancer, as well as tumors in kidney, bone and lungs. Ablative therapies such as ultrasound, radio frequency (RF), microwaves, and laser energy are used to heat the tissue, but most promising method is microwave ablation (MWA). Therefore, the work will concentrate on MWA and this paper presents the finite element analysis of extended tip monopole sliding choke antenna for hepatic microwave ablation (MWA) at quarter wavelength. The heating characteristics, temperature distribution pattern and finite element meshing has been analyzed at frequency of 2.45GHz and at a power of 20 Watt.
