Problems solved by technology

[0003] Existing tags applied to high dielectric constant adhesion surfaces (such as glass, wall plastic, etc.) have a very large sensitivity drop when there is metal nearby, or even close to no performance. However, with the widespread promotion of tags and the expansion of actual needs, Requires a tag that can be used in a normal environment as well as desensitize less than 5dB in the presence of metal

Embodiment Construction

[0009] The specific implementation examples described here are only used to explain the present invention, not to limit the present invention.

[0010] refer to figure 1 , the resistant metal planar label in this embodiment includes an antenna 10, a chip 20 and a substrate 30, the substrate 30 is arranged in a rectangular shape for accommodating the antenna 10 and the chip 20, wherein the chip 30 is arranged at the center of the substrate 30 And the antenna 10 is matched with the chip 20 . It should be noted that the rectangular shape of the substrate is exemplary only, other shapes such as polygonal, elliptical or circular are conceivable in other embodiments. exist figure 1 It also shows the first slit 111 and the second slit 112 arranged mirror-symmetrically with respect to the center of the substrate (that is, the chip 20). In this embodiment, the first slit 111 and the second slit 112 are configured as triangles, but In other embodiments, they may also be flared, quadr...

Abstract

The present invention discloses a metal-resistant flat tag. The metal-resistant flat tag is characterized in that the tag comprises an antenna, a chip and a substrate; the substrate accommodates the antenna and the chip; the antenna comprises a radiation surface, a first slot and a second slot, and a first slot group and a second slot group; the antenna is located at the center of the substrate; the first slot and the second slot, and the first slot group and the second slot group are respectively mirror-symmetrical with respect to the center of the substrate; the first slot and the second slot are arranged in the width direction of the radiating surface and the first slot group and the second slot group are arranged in the length direction of the radiating surface; and the first slot andthe second slot, and the first slot group and the second slot group are obtained by removing the radiation surface material from the rectangular radiation surface. The tag disclosed by the present invention can be applied to the metal-resistant ceramics tag with a long reading distance on the glass surface, and in the presence of metal, the tag has acceptable sensitivity and strong applicability.

Description

Technical field: [0001] The invention relates to an anti-metal flat label, which belongs to the technical field of microwave communication and is suitable for the field of radio frequency identification within the frequency range of 800MHz-1GHz. Background technique: [0002] The RFID system has obvious advantages in storing product information. The product information is stored in the electronic chip of the RFID tag, which can uniquely identify the identity of the product. RFID technology has gained considerable market share and is widely used in contactless payments. Moreover, the Internet of Things system is the development direction of the Internet of Things in the future, and RFID technology is an indispensable part of the Internet of Things system. In the ideal future, every object around us can be interconnected, positioned, and processed through the Internet, and RFID Technology is the foundation of it all. [0003] Existing tags applied to high dielectric constant...
