RFID Antennas for Readers & Industrial Systems

RFID antennas can be used at warehouse portals, manufacturing workstations, conveyors, dispatch points and systems for tracking the movement of materials and assets. Correct antenna placement helps create a read zone suited to the particular process.

Important selection criteria include supported frequency band, polarization, gain, radiation pattern, connector and environmental conditions. The most powerful antenna is not automatically the best choice. The objective is to create the required read zone while reducing unwanted reads outside it.

The antenna operates together with an RFID reader or RFID module. Actual read range and reliability depend on the complete system, including the tag, reader power, antenna quantity and position, tag orientation and surrounding materials.

For demanding installations, the proposed configuration should be tested in the actual operating environment before final deployment. Metal structures, liquids, nearby equipment and movement of objects can significantly affect RFID performance.
