ABSTRACT:
A wheel arrangement includes a wheel having a sensor for measuring pressure in the tyre; a spindle, about which the wheel is rotatably mounted with the aid of bearings around the spindle, and of communication elements between the sensor and elements for using measures, which are associated with the spindle. Communication elements are adapted to a transmission system with a frequency higher than 50 kHz comprising a rotating antenna which is supported by the wheel and a fixed antenna. The two antennae do not have their own rotational guiding element. The antennae are generally annular and disposed in a concentric manner on the same level around the wheel axis (X-X) of rotation, the average radial distance between the antennae exceeding 2 mm.
