The present invention relates to a node in a wireless communication network. The node comprises an antenna arrangement which in turn comprises an array antenna. The array antenna comprises a first set of antenna elements forming a first antenna aperture, and a second set of antenna elements forming a second antenna aperture. The antenna arrangement further comprises a switching arrangement that is adapted to switch between a first mode of operation and a second mode of operation. In the first mode of operation, the first antenna aperture is arranged to generate a first antenna beam. In the second mode of operation, the first antenna aperture and the second antenna aperture are combined and arranged to generate a second antenna beam, the first antenna beam having a wider antenna beamwidth than the second antenna beam. The present invention also relates to a corresponding method. |
