Abstract: Microwave and radio frequency (RF) energies have been used to treat tumors, cancer, arrhythmias etc. The prime goal of ablation technology is to kill the liver tumor while preserving the healthy liver tissue. Microwave ablation (MWA) is a new challenging multidisciplinary technology for the treatment of cancer that has propelled the scientist and technologist to develop the novel microwave antennas to destroy the deep seated tumors. Before designing any novel antenna the preliminary approach is to explore the design requirement of the antenna with respect to a particular application. In this research paper author has explored the interaction of microwaves and the design requirements of miniaturised interstitial microwave antennas for liver tumor.
