Abstract (en)

[origin: WO0103233A1] A variable phase shifter comprising first and second coupled signal conductors (6, 7, 17) providing a transmission path through the phase shifter. The signal conductors are relatively movable to vary the physical length of the transmission path. The first signal conductor comprises a pair of electrically parallel arms (6, 7), and the second signal conductor (17) is arranged between the arms of the first signal conductor. A ground plane (1) is arranged on one side of the signal conductors.
