Abstract: Methods and system using an agile hub and smart connectivity broker for satellite communications are disclosed. In one example, a hub for satellite communications includes an interface to facilitate satellite communications between a terminal and satellites across LEO, MEO, and GEO constellations servicing a geographic region, and one or more processors coupled to the interface. The terminal includes one or more antennas, each antenna having an aperture with a receive portion to receive radio frequency (RF) signals and a transmit portion to transmit RF signals. The one or more processors are configured to implement a broker for the hub. The broker is to plan and facilitate RF links between the terminal and satellites in the constellation based on one more characteristics for satellite communications. The terminal can be a ground-based terminal or a mobile-based terminal on a vehicle, aircraft, marine vessel, or movable machine or object.

Abstract: Antennas such as flat panel, leaky wave antennas with directional coupler feeds and waveguides are disclosed. In one example, an antenna includes a surface having antenna elements, a guided wave transmission line, and a coupling surface. The guided wave transmission line provides a guided feed wave. The coupling surface is between and separates the guided wave transmission line and the surface having antenna elements. The coupling surface controls coupling of the guided feed wave to the antenna elements. The coupling surface can also spatially filter the guided feed wave to provide a more uniform power density for the antenna elements. The guided feed wave can be a high power density electromagnetic wave or a density radially decaying electromagnetic wave.
