Embodiment
Below, with reference to accompanying drawing, a kind of flexible UHF-RFID array antenna of execution mode of the present utility model is elaborated.
Fig. 1 is the schematic diagram of the flexible UHF-RFID array antenna of a kind of execution mode of the present utility model.As shown in Figure 1, positive source and aerial signal carrier wave layer 1 are between bottom surface composite non-metal insulating protective layer 11 and composite non-metal insulation protection interlayer 12; Power supply stratum 2 is between composite non-metal insulation protection interlayer 12 and composite non-metal insulation protection interlayer 13; Logic control bus 3, the banded UHF-RFID days banded UHF-RFID antennas 6 of line options logic control element 5 and zonule in zonule are between composite non-metal insulation protection interlayer 13 and the nonmetal insulating protective layer 14 of surface recombination.
Described nonmetal insulating protective layer (11; 14) be that the material strong by insulating properties, that good stretch-resistance is arranged adopts hot pressing mode to make; for example the PET plastic film wraps up other metal foil belt the array sky tape that becomes a continuous zonule banded UHF-RFID antenna string fully.But each layer function, compound mode, the control model of flexible UHF-RFID array antenna described in the utility model, can decide according to concrete application demand, a present embodiment illustration wherein a kind of execution mode describe, purpose is not to limit the utility model.
