Can anyone tell me about the working of antenna in details including detection and emission.

Does the frequency of resulting radio wave depend upon the frequency of A.C. current flowing in the emitter or the current flowing through it?????

There are many types of antennas.
Here is a link from the EDUCYPEDIA on antennas:
