Being a RFID UHF antenna a "passive" element does it need to be FCC certified? Or, we just need to have the RFID UHF reader certified?


A antenna by itself does not radiate, so can't be certified. The entire unit of a intential radiator, including the antenna, absolutely needs to have FCC certification if you want to legally sell it in the United States.

If this antenna is connected to a receiver-only device that never intentionally radiates, then certification is not required. However, it still must meet the radiation limits for a unintentional radiator, but it is up to you to make sure of that. You don't have to get it tested, but if there is a complaint and the FCC finds it violating the limits, you're in deep doodoo.

  • \$\begingroup\$ I was just poking around on fcc.gov and couldn't find anything relevant either. They seem to be very broadband focused. \$\endgroup\$ – ObscureRobot Nov 3 '11 at 15:52
  • \$\begingroup\$ Also, I am not sure what you mean by fcc.gov being very broadband focused. They have every rule here wireless.fcc.gov/index.htm?job=rules_and_regulations \$\endgroup\$ – Kellenjb Nov 3 '11 at 19:54
  • \$\begingroup\$ If you go to fcc.gov and click on the "Tools & Data" tab, most of that stuff seems to be focused on broadband deployment. I get that the exact rules and regulations are available there. What I would have liked to see is something like a hardware designers RF licensing FAQ which would have a decision tree that points you at the regulations relevant to your project. \$\endgroup\$ – ObscureRobot Nov 3 '11 at 20:06
