Antenna assemblies are described herein. In particular, described herein are multi-focal-point antenna devices and compact radio frequency (RF) antenna devices. Any of these assemblies may include a primary feed that includes a single patterned emitting surface from which multiple different beams of RF signals are emitted corresponding to different antenna input feeds each communicating with the patterned antenna emitting surface. The antenna assembly is therefore capable of emitting beams in the same direction having different polarizations using a single primary feed. Also described herein are compact RF antenna devices having a lightpipe that passes through the single patterned emitting surface.

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.

A mobile terminal, including a display screen, a rear cover facing the display screen, a metal frame, and a circuit board; the metal frame and the circuit board are between the display screen and the rear cover and extend along outer profile of the rear cover. The antenna system includes at least one antenna unit. Each antenna unit includes a first gap in the metal frame and a second gap communicated with the first gap; the first gap extends along perimeter of the metal frame to form a strip-like hollow; the second gap extends from the middle of the first gap toward the rear cover until through the metal frame so as to divide the metal frame into a first section and a second section; the first section and the second section are electrically connected with the feeding point to form a first radiator and a second radiator, respectively.
