摘　　要：设计了一款工作在医疗设备通信服务频段（MICS，402~405 MHz）和工业、科学和医疗频段（ISM，2.4~2.48 GHz）的新型小型化双带植入天线。通过合并一个螺旋辐射带和一个U型辐射带，天线能形成紧凑的双平面倒F （PIFA）结构。包括上下基片层的天线总体积为17 mm×16 mm×1.27 mm。测量的低频带和高频带的–10 dB带宽分别为412~436 MHz和2.4~2.5 GHz。此外，研究了天线的辐射特性及比吸收率（SAR）。A compact dual-band implantable antenna was designed for medical communications services band （MICS, 402-405 MHz） and industrial, scientific, and medical band （ISM, 2.4-2.48 GHz）. By merging a spiral radiating stripe and a U-shaped radiating stripe for metal radiating layer, the proposed antenna can form a compact dual-PIFA structure. The total volume of the proposed antenna including substrate and superstrate is 17 mm×16 mm×1.27 mm. The measured frequency range less than –10 dB at the lower band and upper band are 412-436 MHz and 2.4-2.5 GHz, respectively. In addition, the radiation properties and specific absorption rate （SAR） of the proposed antenna were studied.
