Mechanically controlled phase shifter on a gap-waveguide

The paper is devoted to the study of the possibility of realisation of a phase shifter based on a gap-waveguide in the Ku-band of wavelengths. The results of modelling of the proposed phase shifter design are presented. The phase adjustment range exceeded 360$^\circ$ in the frequency range of more than 30% at a mechanical displacement of the decelerating line by 6 mm. The VSWR of the device was less than 1.1. The proposed phase shifter can be applied for construction of antenna arrays with mechanoelectric scanning.
