Embodiment Construction

[0021] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0022] The present invention designs a novel three-dimensional structure RFID label, which adopts the combined technology of 3D printing and inkjet printing for the first time. The tag is button-shaped and small in size, so it can be easily applied on clothing as a fixed button or a detachable clothing decoration such as a brooch or badge. The tag combines the functions of buttons / decorations and RFID identification / access control. It is easy to use and carry. It is an excellent pass and identity verification tool for fixed groups (military / students / tourists / participants) to enter and exit a specific occasion.

[0023] Such as Figure 1a with Figure 1b As shown, the tag antenna in the present invention consists of a base 1-1, a tag antenna (a dipole bottom structure 1-2, a dipole side structure 1-3, a dipole top structure 1-4) and an RFID chip 1- 5 composition. Th...

Abstract

The invention discloses a novel button-type RFID tag in a three-dimensional structure. The button-type RFID tag comprises a button-type ABS substrate, a bending dipole antenna and a coupling feeding ring. The ABS substrate adopts a 3D printing three-dimensional button structure and comprises a circular top surface, a circular bottom surface and a transitional side wall; the dipole antenna is a combination of a straight line and sector structures on the bottom surface of the substrate, wherein the straight line structure passes through the circle center of the bottom surface and connects the two centrally-symmetrical sector structures in series; one end, away from the straight line, of each sector structure extends to the top surface of the substrate through the transitional side wall; the dipole antenna is also a centrally-symmetrical sector structure on the top surface of the substrate; and the coupling feeding ring is arranged beside the straight line structure of the dipole antenna arranged on the bottom surface of the substrate, and is loaded with an Alien Higgs 4 RFID chip. The button-type RFID tag not only overcomes the plane dimension limitation of a conventional RFID, but also has the advantages of small size, good omnidirectivity, simple structure, low cost, convenient application and wide application range and the like.

Description

technical field [0001] The invention belongs to the field of antenna technology and wireless communication, and relates to a novel button type RFID tag. Background technique [0002] Radio frequency identification is RFID (Radio Frequency Identification) technology, also known as electronic tags and radio frequency identification. communication technology. Commonly used passive RFIDs include low frequency (125k~134.2K), high frequency (13.56Mhz), and ultrahigh frequency (860-960MHz). [0003] As an important part of the RFID system, the RFID tag antenna's performance will greatly affect the efficiency and quality of the entire RFID system. The main factors affecting the performance of RFID antennas include antenna size, operating frequency band, impedance and gain. Currently common RFID is usually a planar structure, and most of them are in the form of bent-line dipoles, which is convenient for reducing the size of the antenna and processing the antenna. The RFID tags us...
