US Classification:

343876, 343700 MS

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.

International Classification:

H01P 5/107

Abstract:

A radio frequency (RF) waveguide housing includes a metal-diamond base with a first surface and a second surface opposite the first surface. The metal-diamond base includes an opening through a thickness of the metal-diamond base, and the opening includes a first side on a side of the first surface of the metal-diamond base and a second side on a side of the second surface of the metal-diamond base. The RF waveguide housing also includes an insert to be inserted in the opening and affixed to the metal-diamond base. The insert defines an interior volume within the opening of the metal-diamond base and a shape of the insert at the first side of the opening is configured to match an end of an RF waveguide coupled to the RF waveguide housing.
