Abstract:
An antenna device comprising:a parabolic secondary reflector having a focal point;a single dielectric substrate, said single dielectric substrate defining a plane;an array of antenna elements mounted on said single dielectric substrate substantially at said focal point of said parabolic secondary reflector, each of said antenna elements comprising a plurality of patches interconnected in a direction transverse to said array; anda scanning control circuit for selecting the antenna elements in a time-sharing fashion wherein each antenna element radiates a beam towards the parabolic secondary reflector at a predetermined angle to said plane when selected by said scanning control circuit, and wherein the beam is reflected by said parabolic secondary reflector as a scanning beam such that as said scanning control circuit selects said antenna elements in said time-sharing fashion said scanning beam scans across said plane.
