Abstract:
1. A phase shifter arrangement for electrically pivoting the irradiation direction of an antenna array which includes two or more radiators having two polarization planes, the phase shifter arrangement comprising two phase shifters which can be altered at the same time, having associated microstrip lines whose electrical length can, in each case, be altered by means of a dielectric which is arranged such that it can be displaced over the microstrip lines, wherein: the microstrip lines of the two phase shifters are arranged parallel and next to one another; and said displaceable dielectric is common to both said two phase shifters for the purpose of altering the electrical length of the microstrip lines of the two phase shifters in the same direction, wherein the microstrip lines extend essentially along a longitudinal axis, and said common displaceable dielectric is displaceable in the direction of the longitudinal axis.
