For the measuring of the electromagnetic interference (e.g.on men) of RF Sinus fields produced by mobile communication equipment field probes are required with high spatial resolution and high sensitivity.Available passive probes show good results with respect to bandwidth and low field distortion, but do not provide the required sensitivity and dynamic range.A significant limitation for active miniature probes is the power supply problem, Plug and Play Remote Starter because batteries cannot be used.

Therefore the effect of high impedance connection lines is examined by a numerical field simulation.Different approaches for the design of an active probe are discussed, a favourable solution with a logarithmic demodulator is implemented and measuring results are presented.
