In the end every antenna receives the EM wave! The EM-wave is the far field. The antenna works in the near field where a dominant component can be the E or M. That depends on the antenna. Between the near and the far field the field is "converted" and local Z0 highly complicated.
As far as I know every antenna declared as whole EM-capable wasn't it and I think it is maybe just impossible to couple directly EM to a antenna <at least if the antenna should be "engineered" which means simple and cheap>. The ferrite antenna couples the M component. The vertical capacitive antenna the E component! Both can be resonant or broadband. The ferrite antenna is highly nonlinear and therefor not suitable as transmitter. As we don't have a "reverse" component for FETs this is even true for the vertical capacitive antenna. And a wire antenna in the classical way is a M component antenna. No ferrites and low Z0 means it can be effectivly used as a transmitting device. - Henry li...@lazygranch.com schrieb:
The ferrite loop antenna receives the magnetic portion of the EM wave. It doesn't have to be a bandpass LC filter. The Wellbrook loop antennas are one example of a broadband antenna that receives the magnetic portion.
