Abstract
An antenna arrangement composed of at least two individual antennas of the same type and each having a pair of signal applying terminals, and a processing circuit connected to the terminals of the antennas for establishing a selected relation between the voltages across the terminals or between voltages derived from these voltages, wherein, for giving the arrangement a desired radiation polarization characteristic, the individual antennas and the circuit are arranged for causing the total radiation pattern of the arrangement to have mirror symmetry with respect to a selected plane.
Claims19
An antenna arrangement comprising at least two individual antennas each having a pair of signal applying terminals and each presenting a frequency dependent polarization characteristics, and circuit means connected to said terminals of said antennas for establishing a selected relation between the voltages across all said terminals or between voltages derived from these voltages, wherein two of said individual antennas each have an asymmetrical radiation pattern and, for giving said arrangement a desired radiation polarization characteristic, one of said two individual antennas is constructed to constitute the mirror image of the other, and said two individual antennas are positioned in mirror symmetry to one another with respect to a selected plane so that their radiation patterns are in mirror symmetry to one another with respect to said selected plane.
