This paper presents the first 3-D printed microwave variable phase shifter. The design methodology for a 3-D printable dielectric flap metal-pipe rectangular waveguide variable phase shifter is first described. Then the measured performance is given, demonstrating a maximum relative phase shift of 143° at 10 GHz, with a near uniform relative phase shift across the whole of Xband and with a low variation in differential-phase group delay.
