Abstract:
Spatial redistributors and methods of redistributing signals in accordance with various embodiments of the invention are illustrated. One embodiment includes an array of channels configured to receive and retransmit a signal, where each of a plurality of independently operating channels in the array includes: at least one antenna element; an RF chain configured to apply at least a time delay to the received signal prior to retransmission; control circuitry configured to control the time delay applied to the received signal by the RF chain; and a reference oscillator. In addition, the array of channels is configured to redirect a signal received from a first set of directions for retransmission in a second set of directions; and the control circuitry of the channels in the array of channels coordinates the time delays applied to the received signal across the array of channels to control the wave front of the retransmitted signal.
