Abstract: An antenna cell for a wide-scan low-profile phased array system includes an antenna layer including one or more stacked conductive radiators configured to receive electromagnetic waves. The antenna cell also includes a feed layer that includes multiple rectangular slots and one or more feed structures. Each rectangular slot may excite an orthogonal polarization. The feed structures are positioned perpendicular to one another, and each of the feed structures includes a feed fork that includes a set of open-circuit stubs and is configured to tune antenna performance.

Abstract: A Digital Multi-Source Multi-Destination Video Multiplexer and Crossbar Device and method which may be applied to a video imaging system, in which multiple input image sources including super-computer-generated digital image scenes, personal computer generated digital image scenes, or any machine with OC-48 fiber optically generated digital scenes are multiplexed, bit combined, and output as a selection of multiple digital video output formats.
