Abstract
A multi-band electronically scanned array antenna including a first sub-assembly having electronic circuits for a first frequency band; a second sub-assembly mechanically coupled to the first sub-assembly and having electronic circuits for a second frequency band; and an aperture adjacent to the first sub-assembly, the aperture being shared by the first sub-assembly and the second sub-assembly. The array antenna may further include a band switching circuit, or a combining circuit for coupling the first sub-assembly or the second sub-assembly to the aperture. The array antenna may also include a third sub-assembly including electronic circuits for a third frequency band. In this way, the aperture is shared by the first sub-assembly, the second sub-assembly, and the third sub-assembly to provide a smaller and lighter array antenna.
