What happens to the fields generated by the antenna at maximum intensity?

At maximum intensity, the fields generated by the antenna are a quarter cycle apart due to the nature of electromagnetic wave propagation. In an alternating current (AC) scenario, the electric field and the magnetic field components of the electromagnetic wave oscillate out of phase with one another, specifically by 90 degrees or a quarter of a wavelength. This phase difference is crucial, as it ensures that both fields can reinforce each other, leading to the maximum strength of the resultant electromagnetic wave.

This phenomenon can be observed in antennas that operate effectively in their designed frequency range, leading to optimal performance and maximum radiated power. The interaction of these fields at a quarter cycle apart is essential for the propagation of the wave through free space. The other options do not adequately describe the relationship between the electric and magnetic fields in the context of maximum intensity.
