HIGH TEMPERATURE RF SURFACE APERTURE

Abstract: a radio frequency surface-aperture, including: a mechanical support structure configured for maintaining mechanical stiffness and strength at a selected temperature; thermal insulation having at least a single layer; one or more through-thickness waveguides located through a thickness of the mechanical support structure and thermal insulation; a cold-side mode coupler arranged to connect a designated cold side of the one or more through-thickness waveguides to an electronic subsystem device; and one or more surface-wave waveguides arranged as an rf antenna on a surface of the mechanical support structure in operative communication with the through-thickness waveguides.
