Impinj Mini-Guardrail Antenna



Specifically designed for demanding item-level deployments, Impinj’s Mini-Guardrail reader antenna operates effectively at read distances of 7.5 cm or less. This antenna is the ideal choice for access control, ticketing, document control, high-speed encoding stations, packaging lines, or any application requiring high reliability and a constrained read zone. Because of its optimized short-range performance, the Mini-Guardrail antenna is virtually immune to the RF-transmission limiting effects of items such as liquids, powders, and metallic packaging.


  • Strong near-field performance for reading tags at a distance of 0-7.5 cm.
  • Small form factor of 70 x 133 x 19 mm.
  • Weak far-field gain to minimize stray reads.
  • Broadband design to enable world-wide operation.
