Abstract: A system includes a sensor device adapted to be associated with a tyre of a vehicle, and a sensor coordinator device adapted to be installed on a body of the vehicle. The sensor coordinator device includes an antenna. The antenna includes a single-piece metallic plate shaped so as to define a first plate portion designed for the wireless reception of data from the sensor device in a first frequency band, and a second plate portion designed for the wireless transmission of data to the sensor device in a second frequency band different from the first frequency band. The antenna further includes a ground plate common to both the first and second plate portions.

Abstract: A sensor device adapted to be associated with a vehicle wheel includes a package enclosing at least one sensor and an electronic data processing apparatus and at least one antenna arranged on the package for at least one among the wireless transmission of data generated by the electronic apparatus and the wireless reception of data to be provided to the electronic apparatus. The at least one antenna is shaped to adhere to surfaces of the package.

Abstract: A method for implementing an electronically tunable structure including: a plurality of elementary cells interacting with the same electromagnetic field; a control unit and a plurality of electronic control devices, each of which is connected to the control unit and to a respective elementary cell. The control unit provide each electronic control device with a corresponding control signal. Each electronic control device is controllable to vary a state of the corresponding elementary cell. The control unit provides control signals such to define a group of identical patterned cells formed by a respective number of adjacent elementary cells. The states of the cells define a predetermined state configuration, so that the states of the group define a periodical sequence of states.

Abstract: A microstrip structure comprising a conductive layer whose width varies in such a way as to obtain an effective dielectric constant, which presents a sinusoidal shape modulation. The propagation of electromagnetic waves in materials with electromagnetic properties, which varies along their propagation direction having desirable characteristics, such as the presence of frequency bands in which the propagation is allowed and of bands in which the electromagnetic waves are stopped.
