The invention relates to a UHF (Ultra High Frequency) tag antenna. The UHF tag antenna comprises a first medium layer, wherein a loop-shaped body made of a conductive material is arranged on the firstmedium layer; a first radiation part and a second radiation part are arranged on a second medium layer; the first radiation part is connected with the middle position of the first side of the loop-shaped body; the second radiation part is connected with the middle position of the second side; the first side and the second side are opposite sides; the first medium layer and the second medium layerare located on the same layer. The UHF tag antenna is provided with double antennas, wherein the loop-shaped body and the first radiation part form the first antenna; the loop-shaped body and the second radiation part form the second antenna; if the performances (such as frequency points, identifiable distances and the like) of the two antennas are different, the UHF tag antenna can provide two antenna services, so that the antenna demands under multiple environment application are met, and the application range of the UHF tag antenna is improved; if the two antennas have the same performances, the two antennas reserve for each other, so that the service life of the UHF tag antenna is prolonged.
Description
technical field [0001] The invention relates to the technical field of communication, in particular to a UHF tag antenna, a manufacturing method thereof, and an RFID radio frequency identification tag. Background technique [0002] RFID radio frequency identification is a non-contact automatic identification technology, which automatically identifies the target object and obtains relevant data through radio frequency signals, and the identification work does not require manual intervention. RFID technology can identify high-speed moving objects and can identify multiple electronic tags at the same time, and the operation is fast and convenient. The general RFID UHF electronic tag antennas on the market are as follows: figure 1 As shown, it includes a loop electric small ring, on the basis of which a conductive pattern is added to form a UHF conventional electronic tag antenna, and an RFID chip is packaged on the loop electric small ring to form an Inlay with radio frequency...
