A method, for manufacturing an electronic assembly, such as an antenna or a capacitive sensing device or a coupled inductor, comprising at least a first electrically conductive element and a second electrically conductive element is presented. The method comprises obtaining said electrically conductive elements, such as patch elements, arranging said electrically conductive elements, such as inside of a cavity defined by a mold structure, at a pre-defined distance from each other for establishing an electromagnetic coupling between said electrically conductive elements, and molding, such as injection molding, a molding material layer at least between said electrically conductive elements, wherein the molding material layer has a thickness between said electrically conductive elements defined by the pre-defined distance. In addition, electronic assemblies, antennas, capacitive sensing devices and coupled inductors are presented.
