Embodiment Construction

[0012] The specific implementation examples described here are only used to explain the present invention, not to limit the present invention.

[0013] refer to figure 1 In this embodiment, the miniature anti-counterfeiting electronic label includes an antenna 10, a chip 20 and a substrate 30, and the substrate 30 is arranged in a circular shape for accommodating the antenna 10 and the chip 20, wherein the antenna 10 matches the chip 20, and the antenna 10 includes a helical monopole 12 and a short-circuit ring 11 , and the short-circuit ring 11 is located on the periphery of the substrate 30 . The spiral monopole 12 is located inside the short-circuit ring and consists of a spiral 121 and a top loading 122 . One end of the spiral 121 is connected with the short-circuit ring 11, and the other end is connected with the top load 122, and the top load is circular. The chip 20 is located on the short-circuit ring 11 .

Abstract

The invention relates to the field of radio frequency identification (RFID) and provides a miniature anti-dismantling electronic tag. The tag includes an antenna, a chip and a substrate. The substrate is arranged into a circular shape and accommodates the antenna and the chip. The antenna is matched with the chip. The antenna comprises a short circuit ring and a spiral monopole, wherein the short circuit ring is disposed at the periphery of the substrate. The spiral monopole is arranged inside the short circuit ring and is provided with a spiral and a top loading. One end of the spiral is connected with the short circuit ring and the other end of the spiral is connected with the top loading, and the top loading is circular. The chip is disposed on the short circuit ring. The miniature anti-dismantling electronic tag of the invention is pasted on an object or packaged in a mold required by a customer during use, the chip is disposed on the short circuit ring, the spiral and the top loading are disposed inside the short circuit ring, the area of the electronic tag can be greatly reduced, the bandwidth can be increased, and chip impedance matching can be conveniently carried out. The electronic tag is small in area and can be conveniently used in various small-size occasions with high anti-dismantling requirements.

Description

Technical field: [0001] The invention relates to a miniature anti-demolition electronic tag, which belongs to the technical field of microwave communication and is suitable for radio frequency identification within the frequency range of 800MHz~1GHz Background technique: [0002] In recent years, with the development of RFID, more and more electronic tags are used in the fields of anti-counterfeiting and anti-tampering. The current brand computers, notebooks, mobile phones, etc., as well as some important documents, files, equipment, etc., all have unpacking and invalidation requirements. The tamper-evident signs printed on shredded paper are easy to copy, and cannot play a very good anti-demolition effect. At the same time, some important equipment needs to be tamper-resistant to screws, and a small-sized tamper-resistant label needs to be used for tamper-proof control. Therefore, effective measures to prevent disassembly are particularly important. UHF electronic tags h...
