ABSTRACT:
Disclosed is an integrated antenna array comprising a plurality of interleaved sub-arrays separately controllable and responding to either the same or separate frequency bands. Both arrays operate with substantially the same phase center and substantially within the same effective aperture. The first sub-array of array comprises of spaced linear radiating elements such as dipoles, log-periodic, Yagi, slotted-waveguide, patch, or array consisting of the same or different elements as used in the first sub-array, either on the same or an entirely different frequency band. Independent beam shaping systems are shown for independent operation of the two arrays.
