Abstract

The invention relates to a multi-antenna RFID (Radio Frequency Identification) circuit. A control module is used for controlling input ends of a first electronic switching switch and a second electronic switching switch to be connected with output ends so as to achieve different connection combinations between the output ends of the first electronic switching switch and the output ends of the second electronic switching switch; the number of antenna modules mounted in connection paths is different under different combinations. Based on the multi-antenna circuit, multiple antenna modules are mounted on a same RFID writing-reading module; the number of the mounted antenna modules is controlled by selection of the paths, so that the size and the cost of the multi-antenna RFID circuit are reduced.

Description

Technical field [0001] The invention relates to the technical field of radio frequency identification, in particular to a multi-antenna RFID circuit. Background technique [0002] Radio frequency identification technology is a wireless communication technology that can identify specific targets and read and write related data through radio signals without requiring mechanical or optical contact between the identification system and specific targets. RFID technology can identify high-speed moving objects and can identify the data of multiple tags at the same time, while the RFID antenna is a transmitting and receiving device for transmitting tag data. [0003] In a traditional RFID (Radio Frequency Identification) circuit, an RFID chip generally only connects one to two antennas. In applications that include multiple antennas, multiple RFID chips need to be used, resulting in a large volume and high cost of the multi-antenna RFID circuit. Summary of the invention [0004] Based on ...
