Electronic label

Abstract

The electronic label is provided with a microstrip circuit and a chip connected to the microstrip circuit on the substrate, and a microwave radiation area in an I-shaped space is provided in the area of ​​the chip microstrip circuit that is generally rectangular in shape. The middle part of the I-shaped microwave radiation area is provided with two horizontal connection circuits connected with the microstrip circuit in parallel intervals, one of which is a continuous connection circuit, and the other is a non-connection connection circuit with discontinuous parts. The chip It is connected across the discontinuous part of the non-communication connection circuit and connected with the non-communication connection circuits on both sides. The electronic label of the present invention can increase the microwave emission / reception distance of the electronic label, and can make the microwave emission distribution of the electronic label more uniform, and after using a chip with a large-capacity memory, the burden on the background operating system is obviously reduced, and information is saved. Reading and writing time saves construction and background maintenance costs and improves management efficiency.

Description

technical field [0001] The invention relates to an electronic tag, in particular to a passive RFID electronic tag which works in the UHF frequency band and has super large memory. Background technique [0002] With the development of the Internet of Things, passive RFID (radio frequency technology) electronic tags are widely used in various social management fields, which can meet the long-distance, multi-object, automatic identification, Analysis and processing have greatly improved management efficiency and level. Due to the structure of the microstrip circuit and the matching degree between the structure of the microstrip circuit and the chip, the traditional RFID electronic tag causes the microwave transmission / reception distance to be short, and due to the small memory of the chip, a large amount of information operations need to pass through the background. Subject to many restrictions in actual use, causing inconvenience. Contents of the invention [0003] In orde...
