What are RFID Antennas?
RFID antennas are used in RFID readers. They're in charge of sending and receiving radio frequency signals that interact with RFID tags. The RFID antenna(s) are housed in the same structure as the RFID handheld and some all-in-one devices. RFID antennas are typically attached to most fixed readers via a coaxial RF connection.
Circular vs Linear Antennas
When selecting the best RFID antenna for your application, you should consider the antenna's polarisation. This may impact the performance of your RFID read zone. An RFID antenna with a circular polarisation generates electromagnetic waves in a spiral motion. Antennas can be circularly polarised in either direction (right or left). The spiral's direction is determined by whether it is turned right or left.
What Antenna Is Best for My Use Case?
When choosing an RFID antenna, you need examine various parameters such as gain, antenna size, antenna beam width pattern, and polarisation. When choosing an application for a use case, start with the read zone you want to target and work your way backwards.
What You Should Know Regarding RFID Antennas
The most expensive antenna isn’t always the best choice for your project. It’s critical to understand the read zone you’re aiming for before selecting the best antenna for the job. This may necessitate on-site testing.
