摘要

设计了一种用于生物医学应用的插入式梳状可植入微带贴片天线。该天线尺寸紧凑，体积为31.46 mm3，工作频率为三种:医疗植入通信系统(MICS) 402 MHz频段用于数据遥测，1.227 GHz频段用于无线电源接收器，2.436 GHz频段用于植入医疗设备(IMD)唤醒信号。天线由DGS (defect Ground structure)组成，DGS支持天线在ISM频段谐振。为了分析实际应用，本设计将射频芯片与天线结合，并采用生物相容性材料硅封装，总体积为245.06 mm3。所提出的DGS植入式天线放置在一层4mm的皮肤内，在各自的频段提供23.6%，12.6%和11.3%的阻抗带宽，具有良好的驻波比值和增益。

A Miniaturized Triple Band DGS Implantable Antenna for Biotelemetry

An inset fed comb-shaped implantable microstrip patch antenna is designed for biomedical applications. The antenna is compact in dimension with its volume of 31.46 mm3and operates at triple frequency: Medical Implant Communication System (MICS) band of 402 MHz for data telemetry, 1.227 GHz for wireless power receiver, and Industrial Scientific and Medical (ISM) band of 2.436 GHz for wake-up signal of implantable medical device (IMD). The antenna consists of Defected Ground structure (DGS) which supports the antenna to resonate at ISM band. To analyze the practical applications, the proposed design incorporates RF chip with the antenna and encapsulated using biocompatible material silicon in 245.06 mm3of total volume. The proposed DGS implantable antenna is placed inside one layer 4 mm skin and provides 23.6%, 12.6% and 11.3% impedance bandwidth at the respective bands with good VSWR value and gain.
