Patent ID: 7336232

Claim:
A dual-band, space fed antenna array, comprising: a feed array comprising a first set of feed radiators for operation in a first frequency band of operation and a second set of feed radiators for operation in a second frequency band of operation; a primary array lens assembly spaced from and illuminated by said feed array by energy in said first and said second frequency bands of operation radiated from said feed array, said primary array lens comprising a first set of radiator elements and a second set of radiator elements operable in said first frequency band of operation, the first set and the second set being spaced apart by a spacing distance, the first set facing to space to form a first radiating aperture for said first frequency band of operation, the second set facing toward said feed array; the primary array lens assembly further comprising a third set of radiator elements and a fourth set of radiator elements operable in said second frequency band of operation, the third set facing to space to form a second radiating aperture for said second frequency band of operation, the fourth set facing toward said feed array.
