Abstract (en)
[origin: WO03063290A2] Disclosed is a phase-shifting system (10) which is used particularly for electrically swiveling the direction of beam of an antenna field comprising several radiators with two planes of polarization. The inventive phase-shifting system comprises two jointly changeable phase shifters (10a,b) with microstrip lines (66, 67) associated thereto. The electrical length of each of said phase shifters (10a,b) can be changed by a dielectric (70) which is slidable above the microstrip lines (66, 67). Such a phase-shifting system offers a simplified design and added functional safety by arranging the microstrip lines (66, 67) of both phase shifters (10a,b) in parallel next to each other and by providing a common slidable dielectric (70) in order to change the electrical length of the microstrip lines (66, 67) of both phase shifters (10a,b).
