An antenna behaves like an RCL circuit.
The R is the radiation resistance corresponding to energy actually radiate. Half come from the E field and half from the B field.
The L and C are responsible for the reactive field close to the antenna. the C tells about the energy stored in the E field attached to the antenna.
The L about the B field.
Do the capacitative and inductive reactive fields store energy in the amount?
Do some antennas have more energy in one or the other? Any example? Can we have an antenna with only inductive reactive field and no C field?
Is it correct to say that the reactive field is time-varying (almost in phase with the source since it is so close) and looks like the electrostatic+magnetostatic field?
thanks
