Antenna

[rckanta]

In EM wave there is two component one is Electric and other is Magnetic.

At the receiver side, Antenna induced a voltage.


Where to get the voltage from Electric or is Magnetic fields?

And How to induced a voltage across antenna?

Remember the EM wave is not stationary.  It moves.   By relativity that is the same as the antenna moving in a stationary wave.  And what does a moving conductor in a magnetic field do?  It generates a current.  Which charges the capacitor that is the antenna.  Giving volts.  Similar results on charge movement from the electric part of the field.  Thinking of it this way also makes it obvious why antenna orientation matters.

" Where to get the voltage from Electric or is Magnetic fields? "

Part of the understanding is you can not seperate electric and magnetic fields in RF , much like a circuit = is one circle or 2 conductors making a loop usually containing components to perform a task .
