Problems solved by technology
[0006] The above method 1 increases the complexity and cost of the reader system, and also brings the difficulty of reader deployment. Method 2 increases the production cost and complexity of the electronic tag. At the same time, the coupling interference between the three tag antennas It is difficult to overcome and greatly affects the recognition effect

Embodiment Construction
[0018] The structure of the present invention is as figure 1 As shown, it includes a housing 1. The housing 1 is made of ABS material or other injection-molded insulating materials. It is a hollow structure with a frame. A label chip 5 is provided in the housing 1. ab, the second frame bc, the third frame cg, the fourth frame gh, the fifth frame he, the sixth frame ea, and the first surface (adhe) of the casing are engraved with a plurality of grooves 2 with certain intervals. The grooves on the first surface adhe are pm and qn, and the enameled wire 3 is embedded in each groove 2 to form a tag antenna 4 , and the start and end ports of the tag antenna 4 are connected to the ports of the tag chip 5 located in the housing 1 . The housing 1 is a regular cube or a rectangular cube. When it is necessary to ensure the consistency of the sensing performance of the electronic tag in the XYZ three-dimensional direction, the housing 1 is a regular cube structure.

The invention discloses an electronic tag supporting three-dimensional identification. The electronic tag comprises a shell, wherein the shell has a hollow structure and is provided with a frame; a tag chip is arranged inside the shell; a plurality of grooves are engraved on the frame and surface of the shell at intervals; an enameled wire is embedded inside each groove to form a tag antenna; and the starting and ending ports of each tag antenna are connected with the port of the tag chip inside the shell. The electronic tag ensures that the tag antennas can be well coupled with a reader antenna when the tag is positioned in any direction of X, Y, Z three-dimensional directions, so that enough energy is sensed from a reader to finish the identification of the tag. The number of winding turns of the antennas can be changed by changing the number of the grooves so as to determine the inductance of the antennas. The induction and the quality factor Q value of the antennas can be finely adjusted by changing the intervals between the grooves. The electronic tag has the advantages of simple manufacturing, low cost, no special requirement on the reader and full compatibility with the conventional market readers.
Description
technical field [0001] The invention relates to an electronic tag, in particular to an electronic tag capable of supporting three-dimensional direction recognition. Background technique [0002] The antennas of the usual forms of electronic tags are all planar structures, and the relative position and direction of the tag antenna and the reader antenna have a great influence on the recognition effect. When the direction of the tag antenna and the reader antenna are parallel, there is the best recognition effect, and when the direction of the tag antenna and the reader antenna is perpendicular, it is basically impossible to effectively identify. [0003] When the application requires that the electronic tag can be effectively identified in the XYZ three-dimensional direction, the usual practice is [0004] 1. The reader uses a multiplexer to connect three or more antennas, so that at least one antenna in any direction of the XYZ three-dimensional direction is parallel to the...
