Abstract

The invention discloses an antenna structure, a reader and intelligent vending equipment. The antenna structure comprises at least one antenna unit, wherein each antenna unit comprises at least two near-field antennas, antenna regions of the two adjacent near-field antennas partially overlap, and each antenna region is a region enclosed by one of the near-field antenna. The antenna structure, thereader and the intelligent vending equipment improve or even avoid the problem that electronic tag reading blind zones exist in a large-area near-field antenna and at transboundary positions of the near-field antennas through adopting the method of partially overlapping the near-field antennas in the same layer, further can reduce or even eliminate reading blind zones on shelves.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular to an antenna structure, a reader and an intelligent vending device. Background technique [0002] Radio Frequency Identification (RFID) technology is a non-contact automatic identification technology. When working, the reader sends a wireless signal of a certain frequency through the read-write antenna. When the electronic tag enters the magnetic field, it sends out the product information stored in the chip by virtue of the energy obtained by the induced current. [0003] At present, radio frequency identification technology has been successfully applied in the field of intelligent vending machines. The usual solution is that a high-power reader is equipped with multiple near-field antennas, and one or two near-field antennas are laid on each shelf, and the products of the vending machine are inventoried by sequentially switching the near-field antennas to ...
