Embodiment Construction
[0012] Referring to the accompanying drawings, the detection device of the present invention includes a tag queue arranged by several radio frequency tags 2 and a substrate 1 for transmitting the radio frequency tags 2 and a detector antenna 3 fixed to the ground and placed above the substrate 1 . The upper surface or the lower surface of the tag queue below the detector antenna 3 is fixed with a metal plate 4 made of tinfoil material and plastic-sealed. A test window 5 larger than the size of the radio frequency tag 2 is provided on the metal plate 4 , and the test window 5 faces the detector antenna 3 .
[0013] When the present invention is in use, a metal plate 4 is attached to the upper surface or the lower surface of the tag queue, and a test window 5 slightly larger than the size of the radio frequency tag 2 is opened on the metal plate 4, and the detector antenna 3 is suspended above the test window 5 and Read the RFID tag 2 towards the window. Since the metal plate 4...

The invention discloses a high-density ultrahigh frequency radio frequency tag detection device and relates to the technical field of radio frequency identification. The device comprises a tag queue formed by arranging a plurality of radio frequency tags, a substrate for transmitting the radio frequency tags, and a detector antenna which is fixed on the ground and is arranged above the substrate. The device is structurally characterized in that: a metal plate is fixedly arranged on the upper surface or the lower surface of the tag queue below the detector antenna; and a testing window of which the size is larger than that of the radio frequency tag is arranged on the metal plate, and is aligned with the detector antenna. Only a specific tag can normally respond to a detector signal by utilizing an electromagnetic shielding technology, and the device has the characteristics of simple structure, long service life of equipment and high detection reliability.
Description
technical field [0001] The invention relates to the technical field of radio frequency identification, in particular to a detection device suitable for high-density ultra-high frequency radio frequency tags. Background technique [0002] RFID is the abbreviation of Redio Frequency Identification, that is, radio frequency identification technology. This technology is a new technology in the field of automatic identification and can be applied in various fields such as logistics tracking and certificate anti-counterfeiting. Ultra-high frequency UHF or even higher frequency RFID tags are the development direction of RFID tag technology. One of the characteristics of UHF frequency band tags is the long read and write distance, which brings great convenience to the application. [0003] Rapid detection of products in the mass production of RFID electronic tags is a problem that needs to be solved. Due to the long reading and writing distance of UHF frequency RFID tags, the detec...
