摘要

本文提出了一种小尺寸、双频可植入环形天线，工作于医疗植入通信服务(MICS)频段(402-405 MHz)和工业、科学和医疗服务(ISM)频段(902-928 MHz)。由于天线是为人体工作设计的，所以涂层采用了SU8生物相容性材料。在工作频段(半径为5.5 mm，高度为0.645 mm)，与现有天线相比，采用弯曲策略可以显著缩小天线的尺寸。模拟带宽在MICS和ISM频段分别为105%和20%。在CST人体模型上对SAR和总效率进行了仿真，显示出良好的性能。

A miniaturized implantable loop antenna at MICS and ISM bands for biomedical applications

This paper presents a small-size, dual-band implantable loop antenna operating in the medical implant communications service (MICS) band (402-405 MHz) and the Industrial, Scientific and Medical service (ISM) band (902-928 MHz). Biocompatible material of SU8 is employed in coating since the antenna is designed to work in human body. By using the meandering strategy, the size of the proposed antenna can be significantly miniaturized compared with the state-of-art ones at the operating bands (radius of 5.5 mm and height of 0.645 mm). The simulated bandwidths are 105% and 20% in MICS and ISM bands, respectively. The SAR and total efficiency are also simulated in CST human model and show excellent performances.
