RFID Antennas: ANFCA-4545-A01 Application Field and Working Principle

RFID, or Radio-Frequency Identification, is a contact-less system for automatically identifying or tracking objects using radio signals. The ANFCA-4545-A01 is a type of RFID antenna, specifically a circularly polarized log-periodic antenna with accurate reading sensitivity. This article will discuss the application field of the ANFCA-4545-A01 antenna and its working principle.

Application Field

The ANFCA-4545-A01 antenna is mainly used for obtaining contactless automatic identification and monitoring of objects. Its is used in places like airports and large warehouses for automatic tracking and identification of packages and goods. Because of its high reading sensitivity, the antenna can read the RFID tags reliably from long distances. It is also usually installed in high-traffic areas, due to its high noise-immunity, which allows it to maintain accuracy even in crowded or noisy environments.

Working Principle

The ANFCA-4545-A01 antenna works on the principle of electromagnetic induction. It consists of a transceiver and an antenna, which generate and receive electromagnetic waves at a specific frequency. When an RFID tag is placed in the vicinity of the antenna, the RFID tag absorbs the transmitted waves, inducing a current in the tag. The tag then modulates this current based on its unique identification code, and sends a signal back to the antenna. The antenna then receives this signal and converts it into a readable code which can be read by the transceiver.

The ANFCA-4545-A01 antenna is a highly sensitive antenna, and can read RFID tags from distances up to 20 meters. It is suitable for most RFID applications, and is an excellent choice for automatic identification and tracking systems.

Conclusion

The ANFCA-4545-A01 antenna is a powerful RFID antenna which enables contactless automatic identification and monitoring of objects. It is mainly used for obtaining reliable readings from long distances in high-traffic areas, and is capable of working accurately even in noisy environments. The antenna works on the principle of electromagnetic induction, consisting of a transceiver and an antenna, which generate and receive signals of a specific frequency. The signal is then received by the antenna, and converted into readable codes by the transceiver.
