Abstract

The embodiment of the invention discloses an antenna, a peripheral circuit, and an antenna system, which are used to form a vertical dipole through a high-isolation first probe and a second probe. The method in the embodiment of the present invention includes: a first-layer antenna, a second-layer antenna, a first probe, a second probe, a first connector, and a second connector, the first-layer antenna and the second-layer antenna The main body of each is respectively attached with a ring-shaped microstrip patch, and a first feed network and a second feed network are built into the ring-shaped microstrip patch of the first-layer antenna; the first-layer antenna passes through the The first feed network and the second feed network are connected to the first probe and the second probe; the first layer antenna is connected to the first connector and the second connector , wherein the first connector corresponds to the position where the first probe is connected to the antenna on the first layer, and the second connector and the second probe are connected to the first layer antenna The location of the antenna connection corresponds to that.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to an antenna, a peripheral circuit and an antenna system. Background technique [0002] Radio Frequency Identification (RFID) technology is widely used. According to some statistics, it is estimated that the market space in the United States will reach 22 billion US dollars in 2020. Wal-Mart, Decathlon large supermarkets and stores all use RFID for cargo management, and even the US train operation system is using RFID for carriage management. [0003] The current RFID technology supports a transmission distance of 10 meters, while the deployment distance of small stations is 20 meters. That is, if you want small stations to support RFID services, you need to increase the transmission distance of RFID to 20 meters. However, the transmission distance supported by the current RFID technology is only 10 meters. The main reasons are the wake-up power of the logo, the receiving sen...
