A radar antenna system comprises a first antenna, an additional first antenna, a second antenna, a guiding section, a branching section, an additional branching section, a filter section and an additional filter section. The branching section and the additional branching section are coupled in series in between the guiding section and the first antenna. The branching section couples the filter section to the guiding section and the additional branching section couples the additional filter section to the guiding section. The guiding section guides energy at a first, second and further frequency. The filter section couples the guiding section to the second antenna, blocks energy at the first frequency and passes energy at the second frequency. The additional filter section couples the guiding section to the second antenna or to a termination, blocks energy at the first frequency and passes energy at the further frequency.
