Radio frequency identification (RFID) technology is a kind of automatic identification technology for non-contact data communication in wireless channels. It is derived from radar technology and is widely used in the Internet of Things. With the rapid development of RFID technology, RFID applications have been widely used in RFID systems such as warehouse logistics, production line management, supply chain management, access control and vehicle management, livestock farming, asset management, item tracing, and food security. In view of the research and practical application of the key technologies of the Internet of Things in recent years, they have shown a good development trend, which has also led to the rapid development of RFID technology. Dawn produces some RFID antennas with frequency of 865 MHz-868 MHz or 902 MHz-928 Mhz. Most RFID antennas type can be customized by your choice. Including different polarization: horizontal, vertical and circular.
