Linearly Polarized Antennas

Impinj Threshold (LP) Indoor RFID Antenna (FCC/ETSI) 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.
