Abstract
Phase correction systems and methods capable of operating in a deployed antenna system are provided. The phase correction system includes a signal generator and a signal coupler. The signal coupler injects a signal at an end of a signal line adjacent an antenna element. Changes in an effective length of the signal line can be detected at a controller that monitors characteristics of the injected signal after it has passed through the signal line. The system can adapt to detected changes in the electrical length by controlling an adjustable phase shifter provided in line with the signal line or by applying suitable post-processing.
