基于种植义齿结构的介质谐振器天线
A dielectric resonator antenna based on implant denture structure
摘要
Abstract
With the rapid development of miniaturized implantable Radio-Frequency(RF)antennas,wireless sensing technologies for human body monitoring have ushered in new opportunities for development.Based on the structure of dental implants,a Dielectric Resonator Antenna(DRA)is proposed.This antenna exhibits good simulation and measurement results,with a resonance at-15.6 dB at 3.82 GHz,and a radiation efficiency of over 97%.When the input power is below 22.8 mW,the Specific Absorption Rate(SAR)meets the requirements for human health and safety.On this basis,the antenna is optimized into a hybrid dielectric resonator antenna with embedded metal.This optimized antenna has higher gain and stronger directivity in its far-field radiation pattern,which can enhance the signal transmission link of the antenna after it is implanted in the oral cavity.Both proposed antennas are small in size and have excellent performance,and they are expected to be implanted in the human oral cavity based on dental implant technology to monitor the oral environment.关键词
