1. First antenna integral with a wheel support for a tire monitoring device which transmits by inductive coupling with a second antenna integral with a wheel, said first antenna comprising:

  • an inductance forming coil;

    a capacitance connected to said coil, said capacitance and said coil forming a resonant circuit; and

    means to clip the flux passing from said first antenna to said second antenna, so as to introduce a non-linear damping of said resonant circuit whereby said first antenna acquires a combination of a high quality factor and a broad pass band.
