ABSTRACT:
An antenna for inertialess scanning a beam through 360 degrees or any desired sector thereof. A reflector, in the shape of a truncated cone that is tangential to an imaginary sphere in the central plane of the cone, is positioned above a feed array located in the equatorial plane of the sphere. The feed array is fed by a network with a plurality of input ports, each of which corresponds to a beam in space. By successively energizing these input ports the beam is caused to scan continuously over the desired sector.
