    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.

    Abstract: A method and a system for transforming between one or more point type sources and a line source in a transmission line structure. A transmission line path controller is inserted between a first parallel-plate waveguide section and a second parallel-plate waveguide section. The transmission line path controller comprises a curved side to which one end of each waveguide is coupled. The transmission line path controller further comprises a waveguide slot, one side of which is a part of the curved side, coupling the waveguide ends that are coupled to the transmission line path controller. The ends of the waveguides that are not coupled to the transmission line path controller forms the point type source and the line source, respectively.

    Abstract: A dual-polarized antenna (10) with good isolation between feed ports (13a, 13b) and high similarity with respect to the radiation patterns is provided. An antenna (10) includes a patch (11), four symmetrically arranged feed structures (12a-12d, 15), two feed ports (13, 13b) and a feed network (14). Radiation pattern similarity is obtained by the pair-wise symmetrical, orthogonal layout of the feed structures (12a-12d, 15). Good isolation between feed ports (13a, 13b) is achieved through a feed network (14) divided into two network parts (14a, 14b) where each network part (14a, 14b) is designed so that each coupling between a network part (14a, 14b) and a feed structure (12a12d, 15) belonging to the other polarization is cancelled by a mirrored coupling with the other feed structure (12a-12d, 15) belonging to the polarization. In addition, a network part (14a, 14b) is laid out so that its corresponding feed structures (12a-12d, 15) are fed with supporting signals of equal magnitude.
