    Abstract: The present invention relates to anode (1) in a wireless communication system, the node (1) comprising at least a first, a second and a third antenna function (2, 2′; 3, 3′; 4, 4′). A first and second downlink signal (Tx1, Tx2), and a first and second uplink signal (Rx1, Rx2) are transferred via said antenna functions (2, 3, 4; 2′, 3′, 4′), which together form a first total antenna function (A1, A1′) and a second total antenna function (A2, A2′). The first and second downlink signals (Tx1, Tx2) are transferred via the first total antenna function (A1, A1′), and the first and second uplink signal (Rx1, Rx2) are transferred via the second total antenna function (A2, A2′). The second downlink signal (Tx2) and the second uplink signal (Rx2) are transferred via a common connection (5, 5′) connected to a filter means (6, 6′) which is arranged for separating these signals (Tx2, Rx2) to connect them to different antenna functions. The present invention also relates to a corresponding method.

    Abstract: An N-element rotational-symmetric array antenna can generate N fixed pencil-beams simultaneously with an omnidirectional beam. An N×N Butler matrix can be used to feed the array antenna, using fewer than N input ports of the Butler matrix to produce the pencil-beams. One or more of the modes generated by the Butler matrix can be individually accessed to produce one or more corresponding omnidirectional beams. The N×N Butler matrix can be driven by a feed network that provides both power dividing and beam-steering, which permits simultaneous generation of the N pencil-beams.

    Abstract: An antenna arrangement includes a number of first radiating elements radiating in a first frequency band and a number of second radiating elements radiating in a second frequency band. The first and the second radiating elements are arranged in different planes. The second radiating elements are arranged in relation to the first radiating elements in such a way that each second radiating element partly overlaps the corresponding first radiating element. Each radiating element has at least one resonant dimension and the resonant dimension of the first radiating element is approximately twice the resonant dimension of the second radiating elements and the second radiating elements radiate at a frequency, or in a frequency band, which is approximately twice that of the first radiating element(s).
