摘要
利用高灵敏度射频无损检测传感器评估样品的电磁特性在航空航天和生物医学等领域应用越来越广泛,提出一种工作在5G频段下的高灵敏度材料无损检测传感装置,该传感装置基于微带型射频电路和矢量网络分析仪。射频电路包括一对T型结功分器、一对交指电容(IDC)和互补谐振环(CSRR)。对该电路加工并对标准样品如PVC、玻璃环氧树脂、FR4等材料测试发现:测量样品的介电特性与已发表文献结果吻合,证明了该无损检测传感装置的高精度和可兼容特性。
The use of high-sensitivity radio frequency non-destructive testing sensors to evaluate the electromagnetic properties of samples is more and morewidely used in aerospace and biomedicine fields.This paper proposes a high-sensitivity material nondestructive detection sensor device that works in the 5G frequency band.The sensor device is designed based on a microstrip radio frequency circuit and a vector network analyzer.The radio frequency circuit includes a pair of T-junction power dividers and a pair of interdigital capacitors(IDC) and Complementary Split-Ring Resonator (CSRR).After processing the circuit and testing standard samples such as PVC,glass epoxy resin,FR4 and other materials,it is found that the dielectric properties of the measured samples are consistent with those of the published data,which proves the high precision and compatibility of the non-destructive testing sensor device.
