Embodiment 1

[0030] The concept of microstrip radiator was first proposed by Deschamps in 1953. Patented in 1955 by French Cutton and Baissinot. The first practical antennas were developed by Howell and Munson, and since then extensive research and development has been done on microstrip antennas and arrays aimed at exploiting their great advantages such as light weight, small size, low cost, conformal structure and compatibility with integrated circuits, etc., which led to various applications, and led to the broad field of microwave antennas, the subject of microstrip antennas was established as an independent entity.

[0031] This embodiment designs a chipless RFID radio frequency tag with a microstrip antenna, which consists of three microstrip units forming an antenna array. The three microstrip antenna units have different resonant frequencies, and the resonant frequencies are close to each other, all in the range of 2.1GHz- In the range of 2.5GHz, select the appropriate side le...

Embodiment 2

[0038] In order to reduce the cost of the label and expand the application range of the label, the chipless RFID radio frequency label can be simplified to a structure with only two antennas. A horizontally planned disc monopole antenna is connected to a vertically polarized dipole antenna. The polarization directions of the antennas are orthogonal, and the polarization diversity also isolates the sending and receiving signals. Frederic Croq et al. have designed a signal layer composed of multiple parallel dipole resonators of different lengths, and a microstrip antenna with aperture coupling feeding, which can achieve three resonant frequencies in the range of 4.5GHz-7.5GHz; Faton Tefiku and others have designed a dual-frequency dipole antenna. The long pair of dipoles work at 0.9GHz, and the short pair of dipoles work at 1.5GHz.

[0039] This embodiment designs a kind of chipless RFID radio frequency label of dipole antenna, and its manufacturing process is as follows: ...

Abstract

The invention discloses a manufacturing technology of a chipless radio frequency identification (RFID) radio frequency tag. According to the invention, a vacuum evaporation method or a cold and hot stamping process is used to manufacture the chipless RFID radio frequency tag. A technology process comprises the following steps: according to a requirement, designing an antenna structure of the chipless RFID radio frequency tag; then taking PVC, PP, PET, paper, a plastic and the like as a base material; using the vacuum evaporation method or the cold and hot stamping process to transfer a conductive metal to a surface of the base material; finally carrying out film coating and packaging so as to obtain the chipless RFID radio frequency tag. The chipless RFID radio frequency tag manufactured by using the above process possesses excellent folding resistance and good toughness. And the tag possesses the following advantages that manufacturing cost is low; an operation technology is simple and easy to operate and so on. A wide application prospect is possessed.

Description

technical field [0001] The invention relates to a manufacturing process of a chipless RFID radio frequency tag, in particular to a process method for making a chipless RFID radio frequency tag antenna by using a vacuum evaporation method or a cold or hot stamping method. Background technique [0002] Radio Frequency Identification (RFID, Radio Frequency Identification) is an automatic identification technology that uses radio frequency signals to carry out two-way information transmission through spatial coupling. It is a non-contact automatic identification technology. It can automatically identify the target object through radio frequency signals to obtain relevant data. The identification work does not require manual intervention. It has the advantages of antimagnetic, waterproof, high temperature resistance, and large storage data capacity. It can be widely used in For example, non-stop charging system, train transportation monitoring system, commodity logistics manageme...
