摘要： An electronic device (200,300) comprising an antenna arrangement with first and second antenna groups with first (122, 142) and a second (124, 144) radiation elements. The first and second radiation elements in each group have first and second respective polarizations and gain, and said groups also comprise a beam forming network (126, 146) connected to the radiation elements of the group and to an output selector (150). The beam forming network (126, 146) of each antenna group uses the radiation elements (122, 124; 142, 144) in the group to create a radiation pattern (127, 147) with a polarization which is a composite of the first and second polarizations of the elements in the group, so that a first (127) and a second (147) radiation pattern of composite polarization is created. The output selector (150) selects or combines signals received by the two antenna groups as its output.
