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.

Abstract: An electronic device with an antenna of the antenna-in-package type (AIP) includes an upper surface on which a radiating element is provided. The radiating element has an open end and a feeding end. The antenna also includes an adaptation element. The antenna is characterized in that the adaptation element is provided at an area that is different from the upper surface of the antenna holding the radiating element. The adaptation element is connected, at one end, to an intermediate point of the radiating element and grounded at another end. The device allows a further size reduction of standard inverted F antennas (IFA).
