ABSTRACT:
A movable portion of an array of antenna elements receives RF signals. A movable ultra-wideband (UWB) transmitter is connected to each antenna element, via a RF to UWB converter. A fixed portion of the antenna array is separated from the movable portion by an air gap. The fixed portion includes one fixed UWB receiver for each movable UWB transmitter. An application system is connected to the fixed UWB receivers. The UWB signals from the movable transmitter are sent across the air gap to the fixed UWB receivers to be processed by the application system as the movable portion rotates.
