▎ 摘　　要

NOVELTY - The sensor structure comprises a medium layer, a microstrip layer (2) and a double circular ring layer-like graphene nitride layer. The medium layer is sequentially arranged from bottom to top. The microstrip line layer is used as an LC resonance cavity, and the GND layer (3) is configured to excite the patch layer to form an equivalent circuit through the excitation of the microstrip to form the equivalent circuit. USE - 5G double-band dielectric constant non-destructive measuring method based on double-complementary open-loop-based surface. ADVANTAGE - The micro-strip line layer makes the high frequency signal can be effectively transmitted, and the signal output end is well matched with the load. The method measures high in precision, convenient for measuring and will not cause loss to the tested sample. At the same time, the method also has the advantages of small volume, simple structure, low cost processing and measuring adaptation. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for G dual-band dielectric constant non-destructive measuring method based on double-complementary open-loop surface. DESCRIPTION OF DRAWING(S) - The drawing shows double complementary ring-surface of the 5 G double-band dielectric constant non-destructive measuring sensor. Microstrip layer (2) GND layer (3)
