Zusammenfassung: | The utility model discloses a UHF garment label. The label comprises a main radiation antenna and an auxiliary radiation antenna, wherein the main radiation antenna is located above the auxiliary radiation antenna. The auxiliary radiation antenna mainly comprises a main antenna, a main chip, and a main antenna substrate. The main chip is connected with the main antenna through anisotropic conductive glue. The main antenna is disposed on the main antenna substrate, and the main antenna is annular. The main chip is located at a side of a vertical central line of the main antenna, and the lateral distance between the main chip and the vertical central line of the main antenna is from 0.5 mm to 5 mm. The auxiliary radiation antenna comprises an auxiliary antenna substrate, an auxiliary arc-shaped antenna, a first auxiliary arm, and a second auxiliary arm. The first and second auxiliary arms are respectively disposed at two ends of the auxiliary arc-shaped antenna. The auxiliary arc-shaped antenna and the first and second auxiliary arms are all disposed on the auxiliary antenna substrate. The label is stable in near-field performance, is good in far-field effect, is good in radiation directivity, and is stable in multi-label intensive reading performance. |
