  • Patent number: 8260336
    Abstract: The present invention relates to methods for adjusting a radiation beam pattern of an antenna arrangement providing coverage in an area. The antenna arrangement comprises an antenna having at least one array of antenna elements connected to a distribution network configured to generate the radiation beam pattern. The method comprises: arranging the antenna elements of said array in at least one column in an antenna plane in relation to a reference plane, each column comprising multiple antenna elements arranged in at least two sub-panels; arranging a motion sensor to the antenna arrangement, said motion sensor is configured to detect deviation of the antenna elements relative the reference plane; and adjusting a beam shape of the radiation beam pattern based on the detected deviation of the antenna to maintain coverage in the area by controlling the distribution network. The invention also relates to an antenna arrangement and base station.
