Antenna arrangement

摘要

In the case of an antenna arrangement having a plurality of antenna groups which are erected in a physically separated manner and consist of a plurality of active individual antennas, only one coaxial connecting cable is connected to each antenna group. Remotely controllable switching means are arranged in the case of each antenna group in order to select an individual antenna. The supply voltage for the antenna electronics and the control information for the switching means are transmitted in a low-frequency manner via the coaxial connecting line which is also provided for the radio-frequency antenna voltage, and are isolated from the radio-frequency antenna voltage by high-pass and low-pass filters.
