“…Unfortunately, this is at the expense of an increase in the diameter of the antenna. To keep the antenna as small as possible, some researchers have proposed to modify the inner structure of antennas such that the sleeves or chokes are implemented inside the antenna [35][36][37]. Further studies showed that the backward heating can be also restrained by adding antenna slots or a cooling system, optimizing the outer conductor structure, or changing the frequency of electromagnetic energy [38][39][40][41].…”

Microwave (MW) antenna is a key element in microwave ablation (MWA) treatments as the means that energy is delivered in a focused manner to the tumor and its surrounding area. The energy delivered results in a rise in temperature to a lethal level, resulting in cell death in the ablation zone. The delivery of energy and hence the success of MWA is closely dependent on the structure of the antennas. Therefore, three design criteria, such as expected ablation zone pattern, efficiency of energy delivery, and minimization of the diameter of the antennas have been the focus along the evolution of the MW antenna. To further improve the performance of MWA in the treatment of various tumors through inventing novel antennas, this article reviews the state-of-the-art and summarizes the development of MW antenna designs regarding the three design criteria.
