UHF RFID Reader Antennas - optimized for Item-Level operation

Impinj's monostatic RFID antennas are designed for operation with Speedway Revolution readers. They have been designed to address tough use cases where a standard patch antenna won’t suffice. Impinj antennas deliver superior system performance for applications ranging from pharmacy, retail point of sale, and race timing.

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
