Abstract: A radiofrequency transmission line configured so as to allow a radiofrequency electrical signal to be transmitted between a first end and a second end, the transmission line including a main conductor and a ground plane electrically connected to an electrical ground of the transmission line. The ground plane includes a set of portions that are connected in series between the first end and the second end and a set of second capacitors, the set of portions including a set of second portions, each second capacitor being inserted between two contiguous second portions.

Abstract: An electrical device includes an electronic control unit including a radio communication interface provided with a planar internal radio antenna housed inside a first housing of the electrical device and including a first radiating element. The electrical device furthermore includes a movable coupling element connected to an external radio antenna, the coupling element being provided with a second radiating element and being able to be moved between a position connected to the housing of the electrical device and a position disconnected from the housing. In the connected position, the coupling element is positioned facing the internal radio antenna while being separated therefrom by an electrically insulating element, the second radiating element being coupled to the first radiating element so as to receive electromagnetic radiation emitted by the first radiating element.

Abstract: The invention relates to a glazing including a glass sheet, one surface of which is covered with a conductive layer. Said glass sheet comprises, at a nonzero distance from the conductive layer, a periodic pattern of conductive elements that is suitable for increasing, for a predetermined frequency, the transmission of radiofrequency electromagnetic waves. Said periodic pattern is selected so as to have a transmission zero at a frequency of between substantially half and substantially double the frequency to be amplified.
