Abstract
An antenna system for receiving radiowaves includes a Lundeburg-type lens which reflects radiowaves to a focal point of the lens. A helical primary feed is located in the proximity of the focal point. Electronic circuitry for processing the radiowaves in a desired manner and the primary feed are supported in a hollow support structure in the proximity of the focal point.
