Abstract
Apparatuses, methods, and systems for beamforming using tunable passive time-delay structures are disclosed. One apparatus includes a node, wherein the node includes a passive time-delay structure, wherein the passive time-delay structure is operative to generate a plurality of delayed signals, wherein each of the plurality of delayed signals is a delayed version of a communication signal, a tunable element, the tunable element operative to introduce a variable delay to the communication signal propagating through the passive time-delay structure, an antenna array, wherein the antenna array generates a beamforming pattern corresponding the passive time-delay structure, and a phase delay adjust control operative to adjust the tunable element of the passive time-delay structure, wherein a direction of the one or more beams of the beamforming pattern changes depending upon tuning of the tunable element.
