Abstract
A phased array antenna may include a substrate and a plurality of phased array antenna elements carried by the substrate, and a plurality of element controllers connected to the phased array antenna elements. Each element controller may be switchable between inactive and active data receiving states. The phased array antenna may further include a plurality of subarray controllers and a plurality of data buses. Each data bus may connect a respective subarray controller to respective columns and rows of element controllers. Further, each subarray controller may cooperate with a respective data bus for sending data in parallel to a plurality of rows of element controllers and while sequentially switching a given column of element controllers from the inactive data receiving state to the active data receiving state
