US Patent 11575204 Interleaved phased array antennas

Technologies directed to interleaved phased array antennas are described. One apparatus includes a support structure, a first phased array antenna, and a second phased array antenna. The first array antenna includes a first set of antenna elements disposed on a surface of the support structure. The first set of antenna elements are located within a perimeter of a first ellipse. The second antenna includes a second set of antenna elements. The second set of antenna elements are located within a perimeter of a second ellipse. The second ellipse partially overlaps the first ellipse. The majority of the second set of antenna elements are located outside the perimeter of the first ellipse. A majority of the second set of antenna are located in the second ellipse in the area not overlapped by the first ellipse.
