I'll give you a nugget that I think is correct.
The radiation efficiency is determined by the cross product of the electrostatic and magnetic fields the electrons are exposed to. No cross product no radiation. AKA why most circuits don't radiate very well.
A dipole is a resonator that generates a large electrical and magnetic cross product. Because it resonates the energy stored/flowing through it is many times the energy being pumped into it.
Lots of things effect the resonance peak of a physical resonator. That's the difference between theoretical antenna's and physical one.
