In this work, two additive manufactured, mechanically tunable microwave phase shifter concepts are introduced. Both are based on WR15 waveguides with non-radiating slots, operating from 60GHz to 65 GHz. Where, the first design achieves tuning through a change in mechanical length, the second relies on variations in the effective material properties. Furthermore, an analytical model for effective rel. permittivity that takes into account the field distribution in the waveguide cross-section was experimentally validated using a low-loss material. The measured figure of merit at the center frequency of 62.5GHz was 751° /dB for the trombone shifter and 852° /dB for the phase shifter based on a movable dielectric.
