Abstract
A phase-shifting system for electrically swiveling the direction of a beam of an antenna field includes several radiators with two planes of polarization. The phase-shifting system includes two jointly changeable phase shifters with microstrip lines associated therewith. The electrical length of each phase shifter can be changed by a dielectric which is slidable above the microstrip lines. Such a phase-shifting system offers a simplified design and added functional safety by arranging the microstrip lines of both phase shifters in parallel next to each other and by providing a common slidable dielectric in order to change the electrical length of the microstrip lines of both phase shifters.
