Innovative Solutions for Real-World Applications

Impinj’s reader antennas evolved as innovative solutions to real world problems. The experience gained in solving customer challenges gave Impinj engineers invaluable insight that has resulted in a family of antennas with characteristics ideally suited for item-level operation.

Specialized Read Zones

Build a robust RFID reader system


Key features of our UHF RFID reader antennas include:

  • Specialized read zones create optimal conditions to read only the desired 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)

Brickyard Antenna

Ideal for point of sale applications

The versatile Brickyard antenna with its confined, short-range read zone has application in point-of-sale terminals, apparel markets, document control, and library systems.

  • Range: Short (30-45cm)
  • Dimensions: 29.5cm D x 6cm
  • ETSI & FCC models available

Guardwall Antenna

Conveyor antenna system

The Guardwall reader antenna provides a tightly controlled read zone and intense RF field, critical to penetrating deep into packed cases traveling on conveyors or packing lines.

  • Range: Long (3m); shorter (variable) when used in pair
  • Dimensions: 70x40x10cm
  • ETSI & FCC models available

MatchBox Antenna

Small and easily integrated in other devices

With its diminutive size, the MatchBox reader antenna is perfect for embedded applications that require unobtrusive RFID capability with short range, well-defined read zones.

  • Range: Very short (<5cm)
  • Dimensions: 73 mm x 33 mm x 12 mm
  • Broadband frequency model

Mini-Guardrail Antenna

Designed for demanding item-level performance

The Mini-Guardrail antenna’s very short read range makes it well-suited for a wide variety of item-level applications. With its four flange-located mounting holes, it fits easily into the guardrail of a line conveyor system, works in a labeling machine, or any other application requiring short range performance in a small form factor.

  • Range: Very short (7 cm)
  • Dimensions: 13x7x2cm
  • Broadband frequency model

Threshold Antenna

Optimized for boundary crossing applications

Initially designed for boundary crossing applications, the Threshold far field antenna, with its planar form factor, provides a consistent and continuous read zone when linearly distributed head-to-tail.

  • Range: Long (4x3m)
  • Dimensions: 46x9x2cm
  • ETSI and FCC models
