Magnetic loop antennas are commonly used for investigations on magnetic fields in a frequency range up to 30 MHz. As for all antennas the antenna factor is the result of a calibration procedure. Commonly used calibration routines like the standard field, standard antenna and three antenna method will be compared to a newer approach called impedance method, first introduced by Ishii [2]. Finally a...
Consideration of the measurement environment of loop antennas is of great importance since loop antennas for low frequency magnetic fields are mostly used under near field conditions. To do this in the right and entire way, the whole measurement set-up has to be taken into account. For this application it would be of great advantage to use a contactless method. As classical calibration methods cannot...
We present a review of available techniques for analysing the crosstalk problem in cable harnesses. An overview of the use of the low frequency model and the multiconductor transmission line (MTL) theory for predicting the crosstalk level in two-cable geometries is presented from the theoretical and practical points of view. A comparison of the results of both techniques against available experimental...
This paper deals with the investigation of interference coupling and transmission characteristics within the frequency range of very high frequency (VHF) voice transmission and navigation systems in airplanes. Possible measuring methods are analyzed for their applicability in the determination of transfer functions. It is revealed that, due to the complex harness with many crosspoints and junctions,...
