This paper presents the outcome of a literature review that an overview of various types of antenna and metamaterial applicator performance towards cancerous tissue or cell for non-invasive hyperthermia cancer treatment (NIHCT) procedure. From the review, it shows that when LHM lens integrated with an antenna, focusing capabilities of the antenna towards the cancerous area can be improved. However, current applicators have a poor focusing effect when directed towards the actual tumor area. In conjunction with that, this paper proposes a new design of modified applicator that is microstrip antenna integrated with left-handed metamaterial (LHM) lens. The antenna termed microstrip-LHM (M-LHM) lens antenna is proposed for use in NIHCT. It is expected to improve the focusing capabilities of an antenna which is used to kill the cancerous area and thus improve the hyperthermia cancer treatment procedure success rate. In addition, this paper provides an overview of heating techniques used in hyperthermia to enhance focusing capabilities and a few metamaterial advantages that can improve the focusing effect and reduced the hot-spots. Specific Absorption Rate (SAR) will be investigated to evaluate the focusing abilities of the proposed applicator using the SEMCAD X Solver.

Interest in the development of hyperthermia for cancer procedure is growth explosively all over the years as it is able to damage and kill the cancer cell non-invasively. An EBG-M antenna is designed with FDTD simulation packages, which is then applied towards treated cancerous area, where for the purpose of this simulation studies, breast is developed as the targeted cancer area to be treated. The radiation absorption is presented as the results obtained to be compared with previous works and also to be analyzed. It has been recognized that the designed antenna or also called as the applicator is able to offer depth radiation absorption and also improved the focusing, which is represented by the specific absorption rate (SAR) distribution towards breast hyperthermia cancer procedure.
