Abstract
A primary feed associated with a focusing system has as its purpose:
-
In transmission, to illuminate the elements of the system (reflector, lens, and so on) with a characteristic function of well-defined amplitude, phase and polarization, in general stable over the required frequency band, and minimizing spillover losses (§9.5.3).
-
In reception, to collect in an optimal manner the energy concentrated by the focusing system at its focus, in the form of a diffraction pattern (§9.8).
