1. An antenna arrangement for mobile radio systems comprising:
an antenna comprising an antenna body and a radiator arrangement, the radiator arrangement being arranged at an upper side of the antenna body; and
an antenna holder and a base plate that is electrically conductive, wherein the antenna holder comprises a base portion, wherein an upper side of the base portion points towards an underside of the antenna body and wherein an underside of the base portion points towards the base plate;
wherein:
only a supporting part of the underside of the antenna body rests on the base portion, so that a receiving space is formed between another part of the underside of the antenna body and the base portion; and
at least the base portion of the antenna holder is electrically non-conductive, whereby the another part of the underside of the antenna body is capacitively coupled to the base plate via the receiving space.
