1. A Mobile communication antenna with at least one dual-polarized radiator, comprising the following features:
a first metal plate arrangement, wherein the at least one dual-polarized radiator is disposed on a first side of the first metal plate arrangement;
a first printed circuit board arrangement is provided, wherein the first printed circuit board arrangement is arranged on a second side of the first metal plate arrangement;
a first free space formed between the first printed circuit board arrangement and the first metal plate arrangement;
the first metal plate arrangement comprises at least one first opening through which a first feed connection for a first polarization of the at least one dual-polarized radiator is passed;
the first feed connection is electrically connected to a first signal line on the first printed circuit board arrangement;
the first feed connection of the at least one dual-polarized radiator is surrounded over the predominant length in the first free space by an electrically conductive first shielding in a non-contacting manner, whereby an E-field is created between the first feed connection and the first shielding during operation of the mobile communication antenna,
a second metal plate arrangement is provided, the first printed circuit board arrangement being arranged between the first and second metal plate arrangements;
the second metal plate arrangement is attached to the first metal plate arrangement and/or to the first printed circuit board arrangement via spacers.
