1results about How to "Guaranteed RF performance" patented technology

The utility model provides a kind of Inlay with multiple label units, the Inlay with multiple label units includes substrate layer, and substrate layer one side pastes aluminium foil antenna layer and forms multiple label units, and there is weak label unit in multiple label units, and the radio frequency performance of weak label unit is lower than standard 3dBm;Substrate layer one side corresponding part of corresponding weak label unit pastes aluminium foil shielding layer, and the aluminium foil antenna layer of weak label unit is located between substrate layer and aluminium foil shielding layer;Or substrate layer other side corresponding part of weak label unit pastes aluminium foil shielding layer, and the aluminium foil antenna layer of weak label unit and aluminium foil shielding layer are separately located in two sides of substrate layer.The utility model solves the problem of how to make the defective product with radio frequency performance lower than standard 3dBm in Inlay can also be rejected in prior art.
