What Is an RFID Antenna?
An RFID antenna is a crucial element of radio-frequency identification (RFID) technology, facilitating contactless reading and writing of data.
This component operates on electromagnetic induction. Radio waves emitted by the antenna activate an IC tag (a small electronic device) using the energy from the waves. Subsequently, the IC tag sends its stored data encoded within the radio waves to the antenna, where it is decoded and read.
RFID technology finds application across diverse sectors such as logistics, manufacturing, retail, healthcare, and transportation. It serves various purposes in logistics for inventory tracking and management, and healthcare for patient identification and medical equipment management, among others. The technology’s contactless nature allows for swift data processing through a series of steps: transmission, response, reception, and decoding. Additionally, RFID systems can hold a wide range of data and are appreciated for their robustness.
