Abstract
Technologies directed to a hybrid-feed network of a parallel feed network and series-fed sub-arrays are described. The hybrid-feed network includes a parallel feed network and multiple groups of series-fed tiles, each tile including a beamforming integrated circuit (IC) and a set of antenna elements.

A panel of an array antenna, the panel comprising:
- a circuit board comprising a feed port and a parallel feed network having a plurality of parallel feed lines;
- a first tile comprising a first beamforming integrated circuit (IC) and a first plurality of antenna elements, each antenna element of the first plurality of antenna elements being coupled to the first beamforming IC, wherein an input terminal of the first beamforming IC is coupled to a first line of the parallel feed lines;
- and
- a second tile comprising a second beamforming IC having an input terminal coupled to a first output terminal of the first beamforming IC, wherein the first tile and the second tile are coupled in series, wherein the parallel feed network comprises:
- a first power splitter coupled to the feed port;
- and
- a set of power splitters, each power splitter of the set of power splitters being coupled to the first power splitter via an equi-length line, wherein the input terminal of the first beamforming IC is coupled to a first power splitter of the set of power splitters via the first line.
