1. A device for measuring an operating variable to be fitted onto a tire, comprising:
an electronic circuit distributed over a first face of an electronic board and which comprises a sensor;
a protective case delimiting an enclosure in which extends at least partially the electronic circuit; and
at least one first antenna wire having one end galvanically connected to the electronic circuit and integrally extending outside of the enclosure so as to project laterally from the protective case,
wherein the protective case is provided with a lateral portion which projects substantially tangentially to a proximal end portion of the first antenna wire in accordance with a generatrix of said first antenna wire.
