Impinj UHF RFID Reader Antennas

At Impinj, we define accurate, reliable, and adaptable solutions as systems of integrity. A system of integrity produces the consistently reliable data demanded as the foundation of any business system. To meet this requirement, high-performance RFID tag chips and RFID readers are a given, but RFID antennas play an equally important role. Reader antennas with characteristics optimized for end-user applications enable the entire RFID system and play a critical role in ensuring that the system operates dependably and accurately.

UHF RFID Antennas for Item-level Operation

Impinj's monostatic RFID antennas with operation optimized for item-level applications enable superior system performance for a variety of deployments, especially when paired with Speedway RFID readers and Monza RFID tag chips.

Key features include:

  • Tightly controlled read zones to minimize reading of stray tags
  • Application-optimized read ranges—short range (near field), long range (far field), or a mix
  • Application-optimized beam width (angle within which most intense energy emanates)
