Impinj Threshold

Threshold-FS Antenna Datasheet

Overview

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.

Read Zone Characteristics

By lining Threshold antennas up along the short edge, one continuous read zone may be established along a boundary line.

The Threshold antenna's wide beam width provides extensive coverage across a boundary edge.

FEATURES

• 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

Electrical Specifications

All electrical characteristics are derived, measured, and tested with the antenna embedded within a polyurethane cable protector. These specifications are not guaranteed if the antenna is used outside of an Impinj-approved cable protector. The specifications are guaranteed at 915 MHz.

Radiation Pattern at 915 MHz (x-y plane)

Please note that all radiation patterns are normalized. See the mechanical dimension drawings to correlate the radiation patterns to the appropriate axes and planes of the antenna.
