Abstract
The present invention relates to an omnidirectional base station antenna arrangement with a number of antenna elements and a number of transceiver means for transmitting and receiving signals to/from a number of user stations. A feeding network is provided which comprises a number of phase ports, a number of which form first phase ports connected to a number of transceiver means for downlink communication and a number of which form second phase ports connected to a number of transceiver means for uplink communication. The feeding network comprises a number of antenna ports connected to antenna elements and the feeding network generates substantially independent, orthogonal signals to provide for phase diversity and the antenna elements are arranged to form at least one cylindrical array antenna. The invention also relates to a method of providing communication between an omnidirectional base station antenna arrangement with a number of antenna elements and a number of transceiver means and a number of user stations as well as to a method of providing for at least phase diversity transmission at an omnidirectional base station antenna arrangement.
