Circuit architecture for distributed multiplexed control and element signals for phased array antenna
The phased array antenna system is described. The phased array antenna system formed on one or more layers of a printed circuit board (PCB). The phased array antenna system be may include a beam forming network to convert between one or more element signals and a beam signal. The phased array antenna system may include one or more control circuits, where each control circuit may receive the element signals for corresponding antenna element. Each of the control circuits may further may establish a control signal path and an element signal path between the antenna elements and the beamforming network, where the signal path may carry multiplexed element and control signals. The control circuits may include a signal adjustment circuit that may adjust the corresponding element signal (e.g., in phase or amplitude) based on the control signal.

The package body has an interconnection structure penetrating the package body. The first circuit layer is disposed on the package body. The first circuit layer has a redistribution layer (RDL) electrically connected to the interconnection structure of the package body. The first antenna layer is disposed on the second surface of the glass carrier.
System and Method for Return End-to-End Beamforming
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.
