Patent attributes
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.
