I understand that in order to most quickly understand all aspects of electromagnetic radiation, the photon representation should be used in some cases and the macroscopic electromagnetic wave representation should be used in others. To preface my question, I want to say that I am pretty well educated in physics and have a bachelor's degree in the subject, so this is purely curiosity driven.
All of that being said, I am curious how a simple dipole antenna generates EM radiation on the level of photons. Again, let me emphasize, I realize this is not the optimal way to understand dipole antennas, I am just curious.
Say you have an AC voltage source connected to your dipole antenna. As the first part of the AC signal starts accelerating the electrons in one direction, I assume photons are being generated already? Considering this is a constantly changing acceleration (the signal is a sine wave, so is the acceleration of the charge), it seems the photons will have many different frequencies. And the exact same scenario stands for the acceleration of electrons in the other direction of the antenna. So are the EM waves that are generated in this fashion, with a macroscopic antenna being fed an AC voltage signal, really just a wide variety of photon frequencies that are mimicking the AC signal's frequency only by landing in the corresponding succession at the receiving antenna?
