Abstract: A composite stack-up for an antenna is described. In one embodiment, the antenna is a flat panel metamaterial antenna. In one embodiment, an antenna assembly comprises an antenna element layer having an upper side and a lower side; a first set of one or more layers forming an upper stack bonded to the upper side of the antenna element layer and being are at least partially transparent to radio frequency (RF) radiation; and a second set of one or more layers forming a lower stack bonded to the lower side of the antenna element layer, where the antenna element layer, upper stack and lower stack are bonded together to form a composite stack.

Abstract: Techniques and mechanisms for providing a low-profile terminal for satellite communication. In an embodiment, a communication terminal includes a radome, an array of radio frequency (RF) elements and a foam layer disposed therebetween. The foam layer includes a first side and a second side opposite the first side, wherein the array of RF elements and the radome are coupled to the foam layer via the first side and the second side, respectively. The communication device provides contiguous structure between the radome and the array of RF elements. In another embodiment, the first side forms a machined surface which contributes to flatness of one or more antenna panels having the array of RF elements disposed therein or thereon.

Abstract: A reconfigurable holographic antenna includes a metamaterial layer and a waveguide with at least one ridge. The metamaterial layer includes an array of tunable slots configurable to form holographic diffraction patterns. A reactance of each tunable slot in the array of tunable slots is individually tunable. The at least one ridge influences coupling between tunable slots in the array of tunable slots. The holographic diffraction patterns formed by the array of tunable slots generate a desired antenna wave in response to a received feed wave.

Abstract: Embodiments of a tool are described. The tool includes an assembly plate having a top surface and a bottom surface. The assembly plate also includes a raised area on the top surface, the raised area centered on a central alignment hole extending from the top surface to the bottom surface through the entire thickness of the raised area. An alignment ring is formed in the top surface of the raised area, wherein the alignment ring surrounds the central alignment hole and is concentric with the central alignment hole. A fitting including a base tier, a plurality of stacked concentric tiers of different radii on a first side of the base tier, and a retainer on a second side of the base tier, wherein an axis of the fitting is adapted to be aligned with the center of the central alignment hole.

Abstract: An apparatus with a rectangular waveguide to radial mode transition and method for using the same are described. In one embodiment, the apparatus comprises a radial waveguide having at least one plate; a radio-frequency (RF) launch coupled to the radial waveguide comprising a rectangular waveguide, a rectangular waveguide to coaxial transition coupled to the rectangular waveguide, and a coaxial to radial transition coupled to the rectangular waveguide to coaxial transition.
