- Abstract:
- 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.
