Abstract
An antenna system is described having at least one LMK antenna which is arranged on a window or another non-conducting part of a motor vehicle and has an antenna capacitance C , and an antenna booster for the LMK reception. The antenna is characterized in that the distance of the antenna conductor(s) to the parts surrounding the LMK antenna is selected in such a way that the value of the harmful capacitance C of the LMK antenna, which is essentially formed by the capacitance between the antenna conductors and the conductive parts surrounding the antenna, is selected to be greater than the value at which the maximum antenna output voltage results, and the value of the harmful capacitance C is selected such that, by increasing the source capacitance of the antenna booster, the signal-to-noise ratio is optimized in the lower LMK range.
