Simulations and Measurements of Coupling Phenomena Between a Radiateing Antenna and a Cable

The paper deals with a problem of near field coupling between a radiating antenna and a cable placed above a ground plane in an open area. This aspect has been formulated as the first phase of Joint Technical Action of COST 286 project, that is interference influence of GSM phones on cabling systems of vehicles. The phenomenon has been simulated for three lengths of the wire (1m, 5m, and 10m), three heights of the wire above a ground plane (5 cm, 30cm and 80 cm), and three orthogonal polarizations of the antenna. The voltage induced in a wire termination has been modelled for the antenna moved along the full length of the wire. Very good agreement of the results obtained by two groups of researches using two different computer codes has been observed. Measurement verification of simulations has been found consuming much time. Therefore validation of modelling has been limited to the wire of 1m length and to two heights of the wire above a ground plane: 5 cm and 80 cm. The results of simulations and measurements are in good coherence.
