FEIG – ID ANT.U LOCFIELD® Antenna
The ID ANT.U LOCFIELD® Antenna is a uniquely flexible UHF RFID antenna designed to create customized reading zones. Its innovative cable-based structure allows it to be shaped into virtually any form — straight lines, circles, meanders, or complex patterns — enabling RFID coverage in spaces where traditional antennas are impractical or uneconomical.
With this antenna, users can tailor the reading field to fit shelves, doorways, machinery, or conveyor systems without performance loss. Its ability to perform in metallic and interference-prone environments makes it a reliable solution for industrial automation, retail, logistics, healthcare, aerospace, and automotive applications.
Easy to install and adjust, the ID ANT.U LOCFIELD® antenna provides a cost-effective and scalable RFID solution that simplifies complex system designs.
