Abstract
A phased array antenna system and method employs a phase delay network to provide a scan angle control signal to respective mixers, with phase delays that correspond to the lengths of delay lines between antenna elements. The mixers are connected in circuit with their respective antenna elements so that the scan angle is controlled by the frequency of the scan control signal, independent of the operating signal frequency for the antenna elements. The system can be tailored for either beam transmission or reception, and is applicable to both single and dual delay network versions as well as multi-dimensional arrays.
