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.
微波（MW）天线是微波消融（MWA）治疗中的关键元件，因为它是将能量以聚焦的方式传递到肿瘤及其周围区域的手段。传递的能量会导致温度升高到致命水平，从而导致消融区域中的细胞死亡。能量的传递，因此 MWA 的成功，与天线的结构密切相关。因此，在 MW 天线的发展过程中，一直关注三个设计标准，如预期的消融区域模式、能量传递效率和天线直径的最小化。为了通过发明新型天线进一步提高 MWA 在治疗各种肿瘤中的性能，本文综述了最新技术，并总结了针对这三个设计标准的 MW 天线设计的发展。
