The invention relates to a monopole antenna () for a motor vehicle wheel unit, comprising a first end (), a floating second end () and a body (), the first end () extending in a first plane (P) and comprising a power supply lug () and a support foot (), the body () comprising a connecting wall (), extending from the first end () in a second plane (P) which is perpendicular to the first plane (P) and connecting the power supply lug () and the support foot () by delimiting a recess (), and a main portion () extending from the connecting wall () to the second end (), the body () being configured so that the center of gravity of the antenna () is substantially in line with the support foot ().

Monopole antenna for a motor-vehicle wheel unit

A system of at least two units that transmit and/or receive a signal at a first or a second frequency, respectively, each of the units being individually connected to the antenna, which is common to a first branch and to a second branch, respectively. The first branch or the antenna includes first passive electronics preventing passage of the signal at the second frequency to the first unit and allowing passage of the signal at the first frequency to the antenna. The second branch or the antenna includes second passive electronics preventing passage of the signal at the first frequency to the second unit and allowing passage of the signal at the second frequency to the antenna.

System of at least two transmitting and/or receiving units connected to a common antenna

A radio-transmitting sensor for a vehicle wheel, suitable for measuring at least one physical quantity and for transmitting a radio signal representative of this measured physical quantity. The sensor includes a measurement and transmission circuit, an antenna impedance matching circuit, and an antenna circuit. The sensor includes a sensitivity switch controlled by the measurement and transmission circuit and suitable for switching the antenna circuit according to two modes: a dynamic mode in which the antenna circuit is configured as a magnetic antenna, and in which the sensor transmits said radio signal representative of the measured physical quantity, this signal including transmitted data frames; and a static mode in which the antenna circuit is configured as an electric antenna.

Radio-transmitting sensor for a vehicle wheel, comprising a dual-mode antenna circuit

A device for near-field communication with a portable user apparatus, includes: a first communication antenna located on a first carrier; a first device for activating the first antenna located on a second carrier, which is facing the first carrier and mechanically connected to the first carrier by pads. The pads are made of conductive metal and the device also includes: a second antenna, a first winding portion of which is located on one end of the first carrier and a second winding portion of which is located on one end of the second carrier, the two ends facing one another. The first portion and second portion of each winding electrically connected by a pad, the second antenna emitting an electromagnetic field, a main component of which is perpendicular to a main component of the electromagnetic field emitted by the first antenna; and a second device for activating said second antenna.

Near-field communication device

A portable radio communication device D' with adjustable total gain and an associated gain adjustment method via a conductive metal frame C situated at the periphery of the portable device D&#x2032;. For this purpose, the frame C includes several metal sections P, P, P, Pnot connected to each other and separated from each other by openings F, F, F, F. Switching elements S, S, S, Smake it possible to electrically connect two consecutive sections in such a way as to modify the length of the sections and to modify the electromagnetic coupling between the antenna A and the metal frame C. The modification of coupling causes a modification of the value of the resultant gain Gr of the antenna A. A calibration step makes it possible to select the sections to be connected together in order to obtain the desired resultant gain Gr of the antenna A.
