A phased array antenna, comprising:
- a panel;
- a plurality of feed boards on the panel, each of the feed boards including at least one radiating element;
- a base-level adjustable phase shifter including a plurality of outputs;
- a first feed board adjustable phase shifter mounted on a first of the feed boards that includes a plurality of radiating elements mounted thereon, wherein the first feed board adjustable phase shifter is coupled to the plurality of radiating elements mounted on the first of the feed boards;
- and
- a first cable that forms a transmission path between a first of the outputs of the base-level adjustable phase shifter and the first feed board.
