A wireless electrical energy transmission system is provided. The system comprises a wireless transmission base configured to wirelessly transmit electrical energy or data via near field magnetic coupling to a receiving antenna configured within an electronic device. The wireless electrical energy transmission system is configured with at least one transmitting antenna and a transmitting electrical circuit positioned within the transmission base. The transmission base is configured so that at least one electronic device can be wirelessly electrically charged or powered by positioning the at least one device external and adjacent to the transmission base.

An article, integrated device, apparatus and a method for mounting a satellite antenna feed structure to an antenna reflector unit. The device comprises, in combination, a housing associated with the feed structure and a cup mounted to the antenna reflector unit. The housing includes a plurality of members projecting radially therefrom, the members being arranged and configured for cooperative engagement with slots correspondingly arranged and configured in the cup, a resilient gasket lining at least a bottom interior surface of the cup. Alternatively, the cup includes a plurality of inwardly projecting members arranged and configured for cooperative engagement with slots correspondingly arranged and configured in the housing. Upon positioning the housing axially relative to, and in mating engagement with, the cup, engaging the members with and sliding them into receiving ports of the slots, rotating the housing such that the members engage with and slide along the slots, and thereby biasing a mating portion of the housing against the gasket lining, the housing is engaged firmly within the cup.

Techniques for communication protocol based on physical configuration of a wireless device are described and may be implemented to adapt to a variety of different wireless scenarios. For instance, configuration of an antenna system of a wireless device is adapted to optimize wireless performance in different physical configurations, such as open configurations and folded configurations. Further, network communications are adapted to optimize wireless communication with a wireless device in different physical configurations of the wireless device. The described techniques, for instance, optimize performance in different frequency bands based on changes in device configuration between open positions and folded positions.

A space-borne antenna system includes a number of panels being moveable to each other and having a gap in between them when the panels are arranged in an operation condition. The system also includes an RF distribution network for providing transmit signals to the number of panels and combining received signals from the number of panels. The system further includes a set of choke flange assemblies that allow a contactless inter-panel signal transmission across a dedicated gap. A respective choke flange assembly is arranged on the far side of a radiating surface of the dedicated adjacent panels. The system also includes an RF seal assembly for suppressing a signal coupling of signals radiated from the number of panels to the set of choke flange assemblies by sealing the gap.

A downhole communication includes an antenna winding fixed to an inner surface of a collar. A fluid flow flows through a center of the antenna winding. The antenna winding is wound around a chassis in an antenna channel in the chassis. The chassis is attached to the inner surface of the collar with a seal such that fluid does not travel between the fluid flow and an annulus between the antenna winding and the inner surface of the collar. A difference in diameter between an upper seal and a lower seal results in a net force to push the chassis against a shoulder on the collar.

A stacked patch antenna is expandable from a thinner stowed configuration in which the gaps between the conductor layers are reduced, to a thicker deployed configuration in which the gaps are expanded to their required dimensions. The expansion mechanism can include rotation of threaded rods, pneumatic expansion of telescoping rods, and/or injection of a gas, a chemical sublimate, and/or an expandable foam into the gaps. In embodiments, the stowed thickness of the antenna can be approximately equal to the sum of the thicknesses of the conductor panels. In some of these embodiments high dielectric layers are not included. In other of these embodiments high dielectric layers are formed by filling gaps with a high dielectric foam. Embodiments implement aperture coupling to the stacked patch antenna. An array of the stacked patch antennae can be folded about a satellite until deployment, and can be planar when unfolded and deployed.

A multi-beam antenna including a reflector having a single reflector surface defining a first focal region and a second focal region. A first feed group located within the first focal region includes a first feed oriented relative to the reflector to define a first beam pointed in a first direction. The multi-beam antenna further includes a fixed attachment mechanism attaching the first feed group to the reflector such that a position of the first feed group is fixed relative to the reflector. The multi-beam antenna further includes a second feed group located within the second focal region that includes a second feed oriented relative to the reflector to define a second beam pointed in a second direction. The multi-beam antenna further includes an adjustable attachment mechanism attaching the second feed group to the reflector, whereby a difference between the first direction and the second direction is adjustable.
