Directional antenna system with electronically controllable sweep of the beam direction

摘要

A directional antenna system with electronically controllable sweep of the beam comprising a radiator arrangement facing toward a reflector and including a switching and control apparatus connected to the radiator and in which very rapid sweeps of the beam direction can be accomplished with high precision and utilizing a large plurality of individual radiators arranged in a matrix with rows and columns and wherein the control and switching apparatus selectively actuates particular ones of the individual radiators such that switching between different groups of radiators causes a change in the beam direction due to the spatial change in position relative to the primary radiator.
