Problems solved by technology

However, in the process of use, it was found that: since the existing electronic tags that can be operated at close range in the above-mentioned occasions all use low-frequency or high-frequency electronic tags, the size of the antenna and the substrate are designed to be large, and they are hidden in books or articles. Among them, on the one hand, it is easy to reveal that the concealment of electronic tags is poor, which is not conducive to the anti-theft of books or articles; Curl and break the antenna, it is easy to damage the electronic tag and not play its due role

Embodiment 1

[0013] Embodiment 1: as shown in Figure 1 and figure 2 As shown, the electronic tag includes an antenna 2 and an electronic chip 3 attached to a substrate 1. The antenna is designed to be long and narrow. In this embodiment, the antenna is connected by a rectangular parallelepiped head 21 and a linear tail 22. , and the length ratio of the cuboid to the line body in the longitudinal direction is 2.2:1. The length of the substrate is 156 mm, its width is between 4 mm, and its thickness is 0.2 mm. The chip adopts a conventional chip that supports various communication protocols, and is integrated with the antenna in a fixed way of bonding or flip-chip.

[0014] When in use, the front of the electronic tag is fixed on the surface of the object to be identified, and is in sealing contact with the object to be identified, so that this embodiment can perform long-distance fast reading and writing on the ultra-high frequency band of 902MHz-928MHz.

Embodiment 2

[0015] Embodiment 2: It differs from the above-mentioned first embodiment in that: the antenna is linear, and the length of the substrate is designed to be 80 mm, the width is 2 mm, and the thickness is 0.1 mm. Such a solution also has a small volume , The characteristics of good concealment. However, when the size of the substrate is smaller than the above data, the size design range of the antenna becomes smaller, and the adjustable range of the electrical length of the antenna becomes smaller accordingly. It is difficult to meet the 915MHz resonance, so that the radiated power emitted by the reader cannot be effectively received. In this way, the reader will consume part of the power as useless work in the space, and at the same time, it cannot read the tag at the optimal distance.

[0016] When in use, the electronic label is packaged on both sides, that is, it is placed inside the book, so that both the front and back sides are in contact with the book without gaps.

Embodiment 3

[0017] Embodiment 3: It differs from the above-mentioned first embodiment in that: the antenna is a strip with toothed edges, and the length of the substrate is designed to be 240 mm, the width is 8 mm, and the thickness is 0.5 mm or 0.8 mm , when in use, it can be applied to larger books or articles by encapsulating it on one side or on both sides.

[0018] Similarly, tests have shown that when the size of the substrate is larger than the above data, although the size range of the substrate can meet the requirements of the antenna design, the increase in the size of the substrate will undoubtedly increase the length, width and thickness when it is embedded in books or articles , reducing the concealment of the antenna, which is not conducive to the anti-theft of books or articles, and also increases the production cost.

Abstract

A linear electronic label includes the antenna and the electronic slug which adhere to the base board. The frequency of the linear electronic label belongs to the superfrequency which the domain is between 902MHz and 928MHz. the antenna is slender, the length of the base board is 80-240mm and the width is between 2-8mm, the thickness is between 0.1-0.8mm. The antenna is made up of the cuboid head and the linear caudal region. So the electronic label can be identified quickly in the superfrequency and the anti-burglary has improved greatly. Also it has the light weight, low cost and is not easy to break the antenna.

Description

technical field [0001] The invention relates to a radio frequency identification technology, in particular to an electronic tag which can be read and written at a short distance and is applied to books and other articles. Background technique [0002] Electronic tags generally include an antenna and an electronic chip attached to the substrate. When in use, the antenna communicates with a reader at a certain distance to automatically identify the target object and obtain relevant data. Because the identification work is fast and convenient, without manual intervention, and can work in various environments, it is widely used in various industries. [0003] When the above-mentioned electronic tags are applied to places such as libraries, bookstores or warehouses, they can better overcome the defects caused by manual operations in the past, and greatly facilitate people's management of books, magazines or warehouses. However, in the process of use, it was found that: since the...
