摘要：

quadrature phase coil in the form of a tube (10) comprising two surface loops of a mirror image of individual coils (20, 30) arranged in such a way that the magnetic field vectors of respective coil loops (20, 30) are substantially perpendicular.an overlapping area between the first and the second loop (20, 30) is adjusted so as to reduce the mutual coupling between the individual coils. the invention also describes the manufacturing process of the sensor coil in the form of a phase quadrature surface probe.
