Abstract
Apparatus for transmitting and/or receiving radiofrequency signals comprising at least a broadband antenna (310) and a substrate (410); the antenna (310) comprising at least a first radiating surface (318) and being superimposed on the ground plane, the ground plane being located on a first face of the substrate (410), at least a side tongue of power supply (314) and at least a side wall (316) connected to at least the first radiating surface (318), the apparatus being characterized in that the side wall (316) is connected to a coupling trace (416) located on a second face of the substrate (410), opposite to the first face of the substrate (410), and the side wall (316) and the coupling trace (416) being configured to act as a capacitive coupling between at least the first radiating surface (318) and the ground plane.
