1. An electronic assembly for a mobile communication antenna comprising an electronic module and a baseplate module with the following features:
the electronic module comprises a substrate, preferably in form of a printed circuit board, wherein the printed circuit board comprises at least one signal line and at least one ground plane;
the baseplate module comprises at least one ground plane and at least one signal conductor, wherein the at least one signal conductor is electrically connected to the at least one signal line of the printed circuit board;
the printed circuit board comprises a first side and an opposite second side, wherein the first side faces the baseplate module;
at least one bushing opening extends through the printed circuit board;
at least one electrically conductive bushing with a first end and an opposite second end is provided, wherein the at least one bushing is inserted through the at least one bushing opening and is galvanically connected to the at least one ground plane of the printed circuit board;
the baseplate module comprises at least one mounting opening;
at least one screw is provided which extends with its screw body through the at least one bushing and engages into the at least one mounting opening of the baseplate module to form a screw connection, whereby the at least one bushing is pressed with its first end onto the ground plane of the baseplate module to form a galvanic connection.
