@mark Come on Mark; you said the antenna "just radiate by electromagnetic radiation, but not needing power themselves." '
If applying power results in the antenna raidiating electromagnetic radiation, then the antenna is clearly an active component.
@mark Not meaning to appear to take @richpowers side, however, this somewhat gets to my point about defining a word. These rules are usually meant to be "gotcha" matters. Depending on how cleaver somebody splits words or does the testing or inspecting has the final say. And I might add that my belief too is the vagueness of these rules permits degrees of graft. (I've seen plenty of that with building inspection and liquor control). So while we can argue engineering, the opponent is thinking graft or making a living defending you as a paid liar, um, lawyer.
Our intent to comply be damned.
A business I now own shares a patent (now expired) with a past customer. I think it was granted on a sensor not because we are great engineers, but because someone parsed words real pretty like.

Yeah "gotcha words" can get ya, like it got me. But where I really got it wrong was by somehow totally ignoring the four words following "the final radio frequency stage".. This had finally occurred to me in the companion thread to this one when https://www.part15.org/community/everything-else/passive-active-electronic-devices/#post-60474 when Roy actually posted the entirety of the rule in the thread and put it right in my face..
Sometimes cant see the forest for the tree..
