This invention relates to an antenna system having a multiple of antenna feeds to drive a microwave lens, composed primarily of a Luneberg lens and a metallic ground plane upon which are mounted three antenna feeds and a shorted stub or four bent-stub coaxial feeds. The antenna system uses a common aperture to provide antenna performance for the three separate feeds, conserving space that would normally be required for three separate high gain antennas.
