A coil antenna is mounted on a circuit substrate. A wiring pattern is disposed on the circuit substrate and connects the coil antenna and a feed circuit. A conductive pattern is disposed on the circuit substrate and located outside a region surrounded by the coil antenna, feed circuit, and wiring pattern. A conductive pattern is disposed on the circuit substrate and located inside the region surrounded by the coil antenna, feed circuit, and wiring pattern. Connection conductors connect the conductive pattern and conductive pattern and are disposed on the circuit substrate. The connection conductor includes interlayer connection conductors.

A light module, a light panel, and a method for transmitting light are provided. The light module includes a light source configured to generate a light and a fiber panel optically coupled to the light source. The fiber panel includes a plurality of optical fibers. The plurality of optical fibers are configured to define two illumination regions such that a controlled light is output from the two illumination regions in diametrically opposite directions.

The radome (10) for vehicles comprises a substrate (18) formed of a radio transmissive resin, the substrate (18) having a proximal face and a distal face and a decoration layer (20) applied to the proximal face, the decoration layer (20) comprising a metalloid or a metalloid alloy deposited on the surface of the proximal face, a transparent frontal cover (22) overlying the decoration layer (20), and a light source (11) that illuminates the substrate (18), so that the light from the light source (11) crosses the transparent frontal cover (22). It permits to maintain its metallic aspect in any lighting condition, so that the decorative function is be improved by adding illumination in appropriate conditions while preserving the radar functionality.

A wireless control device, such as a system controller for a load control system, may comprise a light-transmissive cover for an antenna that may be illuminated to provide feedback to a user of the load control system. The light-transmissive cover may receive light energy from a light-generating circuit to provide a visible display of the light energy. The wireless control device may be mounted to, for example, a ceiling, and the light-transmissive cover may extend from the wireless control device (e.g., down from the ceiling). The light-transmissive cover may be viewed by a user at large viewing angles and at a distance away from the wireless control device, which may simplify and improve reliability of commissioning of the load control system as well as speed up troubleshooting of the load control system after commissioning is completed.

Methods and systems are described for providing end-to-end beamforming. For example, end-to-end beamforming systems include end-to-end relays and ground networks to provide communications to user terminals located in user beam coverage areas. The ground segment can include geographically distributed access nodes and a central processing system. Return uplink signals, transmitted from the user terminals, have multipath induced by a plurality of receive/transmit signal paths in the end to end relay and are relayed to the ground network. The ground network, using beamformers, recovers user data streams transmitted by the user terminals from return downlink signals. The ground network, using beamformers generates forward uplink signals from appropriately weighted combinations of user data streams that, after relay by the end-end-end relay, produce forward downlink signals that combine to form user beams.
