Abstract

An anti-metal ultra-high frequency electronic tag composed of a multi-layer antenna, including a substrate, an antenna receiving/transmitting surface, a ground plane, an ultra-high frequency electronic chip placed on the antenna receiving/transmitting surface, an auxiliary substrate, and an auxiliary receiving/transmitting surface launch surface. The positive and negative poles of the UHF electronic chip are connected to the receiving/transmitting surface of the antenna through the feeder; the receiving/transmitting surface is connected to the ground part isolated by the substrate through one or a row of feeding holes; the auxiliary receiving and transmitting surface is isolated through the auxiliary substrate . When the antenna ground plane is in use, it is directly connected to the metal surface, and the metal surface becomes the antenna ground plane in actual use to achieve the purpose of anti-metal; the role of the auxiliary receiving/transmitting surface is to increase the surface area of ​​the antenna to enhance the electromagnetic wave The effect of energy reception/emission. Such a three-dimensional design can reduce the size of the antenna while increasing the area of ​​the antenna.

Description

technical field [0001] The invention relates to an ultra-high frequency electronic tag, in particular to an ultra-high frequency electronic tag composed of multi-layer antennas that can be directly used on metal surfaces Background technique [0002] RFID is the abbreviation of radio frequency identification technology (Radio Frequency Identification, RFID), also known as electronic tags. Radio frequency identification technology is an automatic identification technology that began to emerge in the 1990s. Coupling (alternating magnetic field or electromagnetic field) realizes non-contact information transmission and achieves the purpose of identification through the transmitted information. [0003] Radio Frequency Identification (RFID) has become a hot topic. According to industry insiders' prediction, the RFID technology market will bring business opportunities of US$3 billion to US$10 billion in new products and services in the next five years, along with servers, data s...
