RFID UHF Antenna Description

Modular slim rugged antenna FlexiRay SFR 2.X with high-quality design and unique radiation pattern enables creation of RFID reading zones in entrances, exits, corridors, doors and gates.

Esthetic and pleasing design allows deploying the antennas in interiors for asset & people tracking in commercial, retail & library applications. Thanks to its modular size, thickness and robustness it is also suitable for applications in light logistics and industrial environment, manufacturing, reading on conveyors and production lines.

RFID Applications

  • RFID portals and reading zones in entrances, gates, doors and corridors
  • Logistics, warehouse aisles, receiving, replenishment and shipping applications
  • Manufacturing, conveyors and production lines
  • Asset tracking in retail, commercial and library applications
  • Access & attendance control

FlexiRay SFR 2.X Antenna Options

FlexiRay SFR 2.X is supplied in various lengths from 585 to 1090 mm, thus allowing optimal adaptation to specific installation. Rugged high-quality aluminum construction was developed for use in logistics, manufacturing and industrial conditions.

RFID UHF antenna FlexiRay SFR 2.X provides flexible mounting capability. The design allows deployment in industrial environments as well as in interiors and offices. Antenna has circular polarization and is available for FCC and ETSI frequencies. Antennas are equipped with robust N-type connector for flexible cable connection.

Antenna with gain 2,5 dBi (5,5 dBic) was designed for middle range applications requiring reading characteristics along the whole antenna length. Using maximum EIRP 2W it can achieve reading distance from 4 to 7 meters*, depending on the type of antenna, used reader, cable length, used RFID tags and environment.

* tested in open air, Alien and Impinj reader 30 dBm, 4m RG-58 cable, Alien Squiggle tag
