Maximum electric and magnetic field strengths at a given distance from some ideal antennas

This paper is about the computation of the maximum electric and magnetic field strengths at a given distance of an antenna, close to the antenna, the maximum being taken over all orientations. We provide closed-form expressions for the maximum field strengths produced in free space by three important ideal antennas: the electric Hertzian dipole, the magnetic Hertzian dipole, and the half-wave dipole.
