Abstract :
This paper reports a fully computer-controlled two-dimensional A4-size electromagnetic noise imaging system with 0.1 mm positioning resolution up over 1.5 GHz. This system can map the near field from printed-circuit boards, personal handy phones, RF transmission lines and so on using a newly developed planar coil array. The 0.1 mm positioning resolution has been realized by a motor-controlled positioning system, and two-dimensional magnetic field mapping is also possible simultaneously for the first time
