Example Embodiment

[0018] The specific implementation examples described here are only used to explain the present invention, but not to limit the present invention.

[0019] Reference figure 1 In this embodiment, the flat X-shaped slot electronic tag includes an antenna 10, a chip 20, and a substrate 30. The substrate 30 is in a rectangular configuration for accommodating the antenna 10 and the chip 20, wherein the antenna 10 matches the chip 20, The antenna 10 includes a radiating surface 11 and a slot composed of an arm one 121 and an arm two 122. The radiating surface 11 is located on the surface of the substrate 30. The slot 12 is provided with two arms, the arm one 121 and the arm two 122 It is set up and down symmetrically. The arm one 121 and the arm two 122 cross into an “X shape”, the intersection is located in the center of the substrate, and the chip 20 is located at the intersection of the arm one 121 and the arm two 122.

[0020] The shape and size of the substrate 30 require specific ...

Abstract

The invention relates to the field of RFID, and provides a plane X-shaped slit electronic tag. The tag comprises an antenna, a chip and a substrate, wherein the substrate is rectangular, and accommodates the antenna and the chip. The antenna is matched with the chip. The antenna comprises a radiation surface and a slit, wherein the radiation surface is located on the surface of the substrate. The slit is provided with two arms which are interlaced with each other to form an X shape, and the two arms are in left-right and up-down symmetry, and the intersection point of the two arms is located at the center of the substrate. The chip is located at the intersection of the two arms. According to the invention, a novel design method for the slit electronic tag is provided, and the method can conveniently adjust the impedance of the antenna, and achieve the conjugate matching with the chip. The chip is fixed on a base material through solidification, and can be pasted on the surface of an object during utilization. Because of the radiation characteristics of a magnetic current element of a slit antenna, the electronic tag is especially suitable for a windshield with a metal explosion-proof film, an object surface coated with metal paint, and a human body.

Description

[0001] Technical field: [0002] The invention relates to a flat X-shaped slot electronic label, which belongs to the technical field of microwave communication and is suitable for radio frequency identification within the frequency range of 800MHz to 1200MHz [0003] Background technique: [0004] With the development of RFID in recent years, electronic tags have been widely used in many fields such as logistics, retail and transportation, which have effectively improved management efficiency and greatly saved labor costs. In some metal-like environments, such as car windshields with metal explosion-proof film, surfaces coated with metal spray paint, human body, animal surfaces, etc., due to the mirror effect, the reflected wave and the incident wave form a standing wave. When the electric field is zero, ordinary antennas cannot obtain energy, and the radiation efficiency is reduced or cannot be read. Microstrip antennas can easily solve this problem, but sometimes due to cos...
