ABSTRACT:
The invention concerns a device for measuring a radiofrequency magnetic field, characterised in that it comprises on a common support: a coil forming a primary reception antenna; a voltage-controlled oscillator, monitored so that its output frequency depends on the amplitude of the magnetic field received on the coil forming primary antenna; an absorption modulation load connected to the oscillator output; a secondary antenna sensitive to the magnetic field influenced by the absorption modulation resulting from the power supply load by the voltage-controlled oscillator, and means for operating the available signal on the secondary antenna.
