1. Antenna array, in particular for mobile communications, comprising:
at least one pair of antenna gaps which are oriented so as to be extend in the vertical direction or predominantly in the vertical direction and are positioned side by side in the horizontal direction, at least one radiator group having at least one radiator is arranged in at least two antenna gaps in each case, which radiator transmits and/or receives in a single polarized, dual polarized or circularly or elliptically polarized manner, the at least one radiator being designed as a broadband radiator such that it can transmit and/or receive HF signals at a relative bandwidth of ≧25%, at least one auxiliary radiator provided in at least two antenna in each case, the at least two auxiliary radiators being arranged such that the centers of the at least two auxiliary radiators are arranged at a horizontal lateral distance that is less than the lateral distance between the centers of the radiator groups or the radiators in the two antenna gaps, the broadband radiators in a particular antenna gap being jointly powered together with the at least one auxiliary radiator, and a distribution network provided for the at least one radiator group comprising the at least one associated radiator which has an associated filter function for the at least one associated auxiliary radiator, which network is designed such that the at least one broadband radiator transmits and/or receives in a broadband frequency range, and specifically at a center frequency that is lower than a comparatively higher frequency band or frequency sub-band having a center frequency which is transmitted or received by the relevant auxiliary radiator. |
