Abstract

The embodiment of the invention provides an RFID label antenna with a metal-resisting characteristic. The RFID label antenna is characterized by comprising an artificial magnetic conductor structure floor, an antenna substrate and an antenna body, wherein the antenna body is attached above the antenna substrate, the antenna substrate is located above the artificial magnetic conductor structure floor, and a printed dipole mode is adopted for the antenna structure.

Description

technical field [0001] The invention relates to the field of radio frequency technology, in particular to an RFID tag antenna. technical background [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] In many RFID applications, in many cases, RFID tags are to be pasted on the surface of metal conductors, or close to some objects with good conductivity. Such as contai...
