RFID HARDWARE – Antennas – CS777 Near Field Circular

CS777 Brickyard Near Field Antenna

The CS777 near-field reader antenna is a key enabling technology for UHF Gen2 Item-Level Tagging systems. The CS-777 is optimized to read near-field tags placed on products with a variety of packaging options including plastic bottles and metal foil blister packs as well as different contents such as powders, pills and even liquids. It can be used in retail and pharmaceutical applications, library systems, document control, check out counters and many other applications requiring a short and constrained read range. The Brickyard antenna is designed for operation with the CSL RFID reader (CS-461), Impinj Speedway® readers as well as other “Powered by Impinj” RFID readers.


  • Near-field RFID operation to enable reading of Item Level Tags
  • Work with UHF Gen2 RFID tags that incorporate an inductive near-field component including the Button™ / Paperclip™ and Satellite™ tags
  • High performance low cost antenna solution
  • Tabletop or table bottom mounting
