Embodiment Construction

[0047] The present invention will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for ease of description, the drawings only show part of the structure related to the present invention, but not all of the structure.

[0048] The antenna structure provided by the embodiment of the present invention is suitable for use in a reader to identify electronic tags, and can be set on a shelf of a smart vending device. Specifically, the antenna structure in this embodiment includes:

[0049] At least one antenna unit, and each antenna unit includes at least two near-field antennas. In the antenna structure, the antenna areas of two adjacent near-field antennas partially overlap. The antenna area is an area enclosed by a near-field antenna. .

[0050] Wherein, the an...

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 embodiment of the present invention relates to the field of communications, 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. At work, the reader sends out a certain frequency wireless signal through the read-write antenna. When the electronic tag enters the magnetic field, the energy obtained by the induced current sends out the product information stored in the chip. [0003] Currently, radio frequency identification technology has been successfully applied to the field of smart vending machines. The usual solution is to equip a high-power reader with multiple near-field antennas, and lay one or two near-field antennas on each shelf to inventory the products of the vending machine by sequentially switching the near-field antennas to read the electronic tags. Once it is detected that the ...
