ABSTRACT:
An antenna, preferably operating in the microwave range, comprising a Luneberg lens with a disc having a radially varying refraction index and provided with feeders distributed around the circumference. Each feeder has the shape of a thin wire the projection of which, as seen radially relative to the center of the round disc, forms a straight line inclined 45.degree. against the plane of the disc. All feeders are inclined in the same direction in their respective radial planes, whereby the feeders opposite a respective feeder will be oriented substantially perpendicular to the feeder permitting passage of radiation to and from the feeder. All of the feeders can be active simultaneously.
