The invention discloses a passive UHF RFID anti-interference capacity testing device which comprises a radiofrequency signal analysis device, an RFID tag reader-writer, an interference source, a combiner, an antenna, a circulator and an anechoic chamber. An input interface of the radiofrequency signal analysis device is connected with a first port of the circulator, a radiofrequency interface of the RFID tag reader-writer is connected with a first input interface of the combiner, a radiofrequency interface of the interference source is connected with a second input interface of the combiner, an output interface of the combiner is connected with a second port of the circulator, a third port of the circulator is connected with the antenna, the antenna is arranged in the anechoic chamber, a to-be-tested tag is placed in the anechoic chamber and is spaced from the antenna by a preset distance. The passive UHF RFID anti-interference capacity testing device has the advantage of realizing testing on anti-interference capacity of passive UHF RFID tags.
Description
technical field [0001] The invention relates to the technical field of radio frequency tags, in particular to a passive UHF RFID tag anti-jamming ability testing device and method. Background technique [0002] Radio frequency identification technology is a wireless, non-contact automatic identification technology that emerged in the 1990s, and is a cutting-edge technology project developed in recent years. This technology mainly uses radio frequency signals to realize non-contact information transmission through spatial coupling and achieve the purpose of identification through the transmitted information. The remarkable advantage of radio frequency identification technology is non-contact, so no manual intervention is required to complete the identification work, it can realize automatic identification and is not easy to be damaged; it can identify high-speed moving radio frequency tags, and can also identify multiple radio frequency tags at the same time, and the operatio...
