ABSTRACT:
A multi-band wide-angle scan phased array antenna with novel grating lobe suppression has a first plurality of radiation elements for radiating a first frequency arranged in a rectangular configuration. A second plurality of radiation elements for radiating second frequency are arranged in a rectangular frame around the first radiation elements. A third plurality of radiation elements for radiating third frequency are arranged in a rectangular frame around the second radiation elements. The radiation elements are apertures that are λ/2 of an operating frequency in size. The radiation elements may also be arranged in square, circular, or elliptical configurations.
