Mobile radio system with a beamforming network and a multiple antenna system to generate a broadcast beam and a corresponding method for this

摘要

A mobile radio system (1) comprises a beamforming network (2) and a multiple antenna system (3) for generating a broadcast beam (11). The multiple antenna system (3) comprises a first group (4a) of n-type radiator arrangements (4a, ..., 4a) and a second group (4b) of n-type radiator arrangements (4b, ..., 4b). The beamforming network (2) is electrically conductively connected to the multiple antenna system (3) and, via the first group (4a) of n radiator arrangements (4a,..., 4a), a first group (8a) of non-overlapping radiating elements is formed. or receive lobes (8a, ..., 8a) and via the second group (4b) of n radiator arrangements (4b, ..., 4b) a second group (8b) of overlap-free radiating or reception lobes (8b, 8b, 8b), the position of the emitting or receiving lobes (8a, 8b, 8b, 8b, 8b, 8b) being set in such a way that between two adjacent emitting or receiving lobes (8a, 8b), ..., 8a, 8b, ..., 8b) of one group (8a, 8b) a radiation or reception lobe (8b, ..., 8b, 8a, ..., 8a) of the other group (8b ; 8a).
