Abstract
A phased array antenna may include a substrate and a plurality of phased array antenna elements carried by the substrate. The phased array antenna may also include a plurality of antenna element controllers for the phased array antenna elements and a central controller for providing beam steering commands and edge trigger synchronization signals for the antenna element controllers. Furthermore, each of the antenna element controllers may store a respective next beam steering command and implement the respective next beam steering command as a respective active beam steering command responsive to the edge trigger synchronization signal from the central controller. The edge trigger synchronization signal may be delivered substantially simultaneously to all of the antenna element controllers, and each antenna element controller may detect the edge trigger synchronization pulse only during a predetermined time window, for example.
