Far-field retarded potentials
Antenna models — reading order Maxwell’s equations Retarded potentials Near-field / far-field boundary Far-field retarded potentials (this article) Array pattern multiplication Dipole power gain patterns Introduction In the Fraunhofer region the amplitude goes as \(1/r\), and the phase is \(e^{-jkr}\) times a linearised path through the source. The angular part factors into a radiation vector … Read more
