Abstract: In an example embodiment, a system comprises a chain of serially coupled nodes, including a central processing node (CPN) and one or more radio communications nodes (RCNs). The CPN couples to a first RCN in the chain via a dielectric waveguide (DWG) link and any further RCNs in the chain are successively connected in serial fashion from the first RCN via further (DWG) links. The CPN generates outbound radio carrier signals that are waveguide-propagated in a downstream direction of the chain, for over-the-air (OTA) by targeted ones of the RCNs, while radio carrier signals received via OTA reception by respective ones of the RCNs are waveguide propagated as inbound radio signals in an upstream direction of the chain, for processing by the CPN. Advantages from he contemplated system include greatly simplified implementation of the RCNs, with lower cost and power consumption. Further, strategic placement of failover CPNs and DWG links provide for continued operation in the face of CPN or DWG link failures.

Abstract: In an Advanced Antenna System, a desired power amplifier, PA, load distribution, which counters the mismatch of active impedance load, is achieved by altering the lengths of routing traces connecting PA outputs and corresponding antenna elements/subarrays. The combined output performance in the beam during active impedance load is then restored to the matched condition performance. This can be visualized as distributing the load impedance more evenly—ideally, on a circle—on a Smith chart.
