Embodiment Construction

[0030] The embodiment of the present invention will be explained in detail below in conjunction with the accompanying drawings. The examples given are only for the purpose of illustration, and cannot be interpreted as limiting the present invention. The accompanying drawings are only for reference and description, and do not constitute the scope of patent protection of the present invention. limitations, since many changes may be made in the invention without departing from the spirit and scope of the invention.

[0031] In order to achieve multiple performances on a UHF RFID tag, an embodiment of the present invention provides a UHF RFID tag with variable performance, which is provided with an etched antenna layer and a guide line, such as figure 1 Perspective view shown:

[0032] The etched antenna layer includes the main antenna 1 and the additional antenna 20 separated from the main antenna 1 , the guiding line is arranged in the area where the additional antenna 20 is loc...

Abstract

The invention relates to the technical field of ultrahigh-frequency RFID, and particularly discloses a performance-variable ultrahigh-frequency RFID tag which is provided with an etching antenna layer and a guide wire, the etching antenna layer comprises a main body antenna and an additional antenna separated from the main body antenna, and the guide wire is arranged in the area where the additional antenna is located; and the additional antenna is connected with the main body antenna in a manner of folding along the guide line. The main body antenna and the additional antenna can be conducted by limiting the proportion, the size and the position of the guide wire, a new antenna is formed, the length of the main body antenna is enlarged, and the performance is expanded; when the tag is pasted on an object according to an original shape, namely when the tag is not folded (an initial tag), only the main body antenna plays a role, and the main body antenna is short in size, low in performance and suitable for application scenes of short-distance reading and writing; according to the invention, the additional antenna is arranged to be a plurality of segmented antennas, and a guide wire pair is arranged corresponding to each segmented antenna, so that the segmented gradual extension of the main body antenna is realized, and the requirements of different performances of the ultrahigh frequency antenna are met.

Description

technical field [0001] The invention relates to the technical field of ultra-high frequency RFID, in particular to an ultra-high frequency RFID tag with variable performance. Background technique [0002] RFID technology is a very important technology since the birth of the Internet of Things. It is widely used in the acquisition and transmission of information. In recent years, due to the development of network technology, coupled with the convenience and low cost of RFID, this technology has also been pushed trend. RFID can be used in many occasions, some for batch inventory, some for long-distance reading, and some for identity verification. Each application has different performance requirements for RFID. The market generally uses the method of replacing RFID tags for different application scenarios, and the way of replacing tags makes it difficult to build inventory. Every time a new application is encountered, production needs to be switched immediately, which makes t...
