Embodiment Construction
[0017] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0018] Such as figure 1 with figure 2 As shown, in an embodiment of an antenna and an electronic tag suitable for different protocols or types of electronic tag chips of the present invention, the antenna includes a substrate and a coil arranged on the substrate, and the coil is arranged on one side of the substrate (see figure 1 ); the coil is a helical coil composed of lines 1 formed by copper foil on the substrate; the head 11 of the helical coil is arranged on the edge of the substrate, and gradually extends to the middle position of the substrate along the edge of the substrate , the tail portion 12 of the helical coil is arranged in the middle of the substrate. Compared with the head 11 of the helical coil, the tail portion 12 of the helical coil is closer to the center point of the above-mentioned substrate, but not necessarily On the center po...

The invention relates to an antenna applicable to electronic tag chips using different protocols or having different model numbers. The antenna comprises a base plate and a coil arranged on the base plate, wherein the coil is arranged at one side of the base plate, and is a spiral coil consisting of lines formed by copper foils arranged on the base plate; the head part of the spiral coil is arranged at the edge of the base plate, and gradually extends to the middle position of the base plate along the edge of the base plate; each the middle part and the tail part of the spiral coil is provided with at least one electronic tag feeding bridge; and each electronic tag feeding bridge is passes through the base plate through a metalizing through hole to be connected with a metal bridge arranged at the other side of the base plate; the metal bridge is also connected with the head part of the spiral coil through the metalizing through hole. The invention also relates to an electronic tag. When the antenna applicable to the electronic tag chips using different protocols or having different model numbers and the electronic tag provided by the invention are used, the beneficial effects of few antenna types and low management and production cost are achieved.
Description
technical field [0001] The invention relates to the field of radio frequency identification, and more specifically relates to an antenna and an electronic label suitable for different protocols or types of electronic label chips. Background technique [0002] With the promotion and popularization of NFC technology, the market of HF13.56MHz electronic tags is getting bigger and bigger, and it has been widely used in various fields. After years of development, this frequency band tag chip has been very mature in all aspects. However, there are multiple protocols in this frequency band tag technology. The current mainstream protocols are: ISO / IEC14443-A / B and ISO / IEC 15693. Usually, even if the chip is produced by the same manufacturer, the capacitance of the chip with different protocols is also different, which requires the design or selection of antennas with different inductances to match the electronic label chip with different protocols, so that the electronic label chi...
