Small round PCB UHF anti-metal RFID tags are ultra-compact, rugged RFID identifiers designed specifically for metallic environments. Built using FR4 or ceramic-based printed circuit boards, these tags feature a tuned antenna structure and integrated isolation layer, enabling reliable performance even when affixed directly to metal.
With diameters as small as 10mm–25mm, they are ideal for tagging tools, surgical instruments, metal components, and IT equipment where space is tight and read performance must not be compromised.
Technical Highlights:
UHF frequency: 860–960 MHz (EPC Gen2 / ISO 18000-6C compliant)
Optimized for on-metal performance
Constructed from durable PCB substrates (FR4/ceramic)
Read range: Up to 1–3 meters (depending on size and reader)
Diameter: Typically 10mm–25mm; custom sizes available
Mounting: Adhesive, rivet, or embedded into metal fixtures
Operating temperature: -40°C to +150°C
