Abstract: The antenna combination has at least two individual antennas which form part of at least one resonant circuit which appears on an electrically conductive surface. The output signals of the individual antennas are combined, for example, added. The antennas are preferably located at the edges of the electrically conductive structure. The antenna combination of the invention is particularly suitable for transmitting and receiving in vehicles because antennas which have transmitting and receiving properties equivalent or superior to those of rod and disc antennas can be built into the vehicle. The antenna combination can be used advantageously in a diversity process.

Abstract: According to the receiving method for mobile reception has a plurality of individual receiving antennas, also known as diversity receiving method, on the individual antenna output signals an auxiliary modulation is superimposed and the antenna output signals are added to give a summation signal which as amplified selected intermediate-frequency summation signal is then demodulated in relation to amount and frequency or phase, the phase position of an individual signal in relation to the phase position of the summation signal and/or the amplitude contribution of an individual signal to the amplitude of the summation signal thereby being determined. This information is utilized for optimizing the useful signal with a view to optimum interference suppression for example in that the phases and/or amplitudes of the high-frequency individual signals are changed in dependence upon the phase position and/or amplitude contribution determined.
