Paine T O Administrator of the National Aeronautics and Space, N A, Seaton Arthur F: Conical reflector antenna. November 23, 1971: US3623114 (144 worldwide citation)

A conical reflector antenna is disclosed with a feed that is either a close approximation to a line source or a cylindrical structure which is electrically equivalent to a line source. Nearly complete control of its aperture illumination function is achieved by exciting various amounts of the line s ...

Seaton Arthur F: Dual reflection mirror scanning antenna system. Hughes Aircraft Co, June 11, 1993: JP1993-145334

PURPOSE: To eliminate the need for a scanning element to scan an antenna beam over an angle the same as a beam scanning angle by changing a tilt angle between a main longitudinal axis and a sub reflection mirror longitudinal axis so as to rotate a sub reflecting mirror around a rotating point with r ...
