Impinj Threshold Antenna

Impinj Threshold-FS Antenna


Initially designed for boundary/threshold crossing applications, the Impinj Threshold antenna has a very wide beam width to maximize zone coverage. Threshold antennas provide a consistent and continuous read zone when linearly distributed head-to-tail. At 46 x 9 x 2 cm, the Threshold antenna's planar form factor fits readily onto fencing or other borders.


  • Strong far-field performance.
  • Wide beam width to maximize zone coverage.
  • Low profile form factor of 457 x 89 x 19 mm.
  • Optimized performance for operation from 902 - 928 MHz.
