Abstract: An antenna array for use with an X-band weather radar system comprises a printed circuit board, a plurality of antenna elements, and a plurality of integrated circuit packages. The printed circuit board includes a first side and an opposing second side. The antenna elements are configured to transmit and receive radio waves at frequencies in the X-band. The antenna elements are electrically connected to the first side of the printed circuit board and positioned thereon in a two-dimensional array. A center of each antenna element is located on a point of a grid with grid points orthogonally spaced apart. Each integrated circuit package includes a transmitter electronic circuit and a receiver electronic circuit that are each in electronic communication with one antenna element. Each integrated circuit package is positioned on the first side of the printed circuit board to underlie one antenna element.
