  • Reception antenna for optical image formation device using nuclear magnetic resonance
    Patent number: 4792760
    Abstract: In the invention, the quality of the signal received is improved by symmetrizing the antenna. To this end, this antenna comprises two cords each of which has a symmetry with respect to one and the same plane (XOZ). These cords are linked by their ends to antenna tuning capacitors. The received signal is taken up by a high-frequency line integrated to one of the cords at the connection point of one of the tuning capacitors. Furthermore, the other end of this high-frequency line, arranged in the plane of symmetry, is linked to an impedance amplifier-transformer circuit with a high input impedance.
