An infinitesimal / horizontal dipole antenna is placed at the height of 1.5 2 above a perfect conducting plane. Find all e (theta) directions (in the range from 0 to 90 degree) in which the radiation from the isotropic antenna and its image are in phase and thus gives maxima and all O (theta) directions (in the range from 0 to 90 degree) in which the radiation from the isotropic antenna and its image are 180 degrees out of phase and thus forms nulls. What should be the height h, if it is essential to have no side lobes except at 0 = 90⁰.
