Abstract: A phased-array antenna assembly includes an antenna board stack, a radome configured to cover the antenna board stack, and a casing configured to support the antenna board stack. The antenna board stack includes a central core, a bottom antenna unit defining a bottom thickness between a bottom surface of the central core and a bottom end of the antenna board stack, and a top antenna unit defining a top thickness between a top surface of the central core and the top end of the antenna board stack that is substantially equal to the bottom thickness. The bottom antenna unit includes two spaced apart bottom metal layers each associated with a different distance from the axis of symmetry. The top antenna unit includes two spaced apart top metal layers each associated with a corresponding one of the distances from the axis of symmetry associated with the bottom metal layers.

Abstract: A method including identifying clusters of antenna elements of a phased array antenna. For each cluster of antenna elements, the method includes identifying a reference antenna element of the cluster of antenna elements and identifying pairs of calibration antenna elements of the cluster of antenna elements. For each pair of calibration antenna elements, the method includes executing a calibration routine configured to determine a calibration adjustment for each antenna element of the pair of calibration antenna elements based on the reference antenna element. The method also includes determining a leveling adjustment for each antenna element of the phased array antenna. The method further includes adjusting the element gain and the element phase of each antenna element of the phased array antenna based on the corresponding leveling adjustment to equalize a transmission gain and a transmission phase of each signal path of the phased array antenna.
