Embodiment Construction
[0030] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0031] Such as figure 1 As shown, a magnetic resonance coupling space high-frequency magnetic field intensity measurement device includes a coil installation slot A, a connector B and a signal processing circuit printed board C, and the induction coil is installed in the circular groove of A. In this example, the induction coil is wound with a coaxial cable. In order to take into account the frequency band and sensitivity of the induction coil, the number of turns of the induction coil is set to 1 turn, the radius of the coil is 2.5cm, the radius of the coil wire is 0.4mm, and the coil inductance 100nH. The above C is vertically connected to A through the connector B, that is, the signal processing circuit printed board C is perpendicular to the plane where the induction coil is located, so that the magnetic field generated by C is perpend...
