I am building a 125kHz Near-Field Magnetic Induction Communication system and so will be using ferrite cored inductors for the transmitter and receiver. I am worried about RF radiation as it pertains to the conformance of FCC part 15. I haven't been able to get any good info on how an inductor/solenoid emits electromagnetic radiation. I have read things that allude to the inductor being quite poor as a typical antenna. I have also read things that allude to the reason for it's poor performance is because NFMIC systems generally use lower power than an RF system. I read a bit on helical antennas and an inductor, at 125kHz, would definitely be a normal-mode type, radiating in all directions.
I don't know much of the equations and math involved and am hoping to get a quick and dirty answer. If I can't get an answer without learning the math, then so be it, but I want to see what you guys have to say.
Thanks,
Andrew
