摘要
In this paper, a mechanically steered phase shifter with planar structure is presented for Ka-band satellite user terminals. The proposed phase shifter is composed of a power divider based on ridge gap-waveguide (RGW) and a phase-shifting section based on double-layer groove gap-waveguide (GGW) with a shared rotatable plate. The simulated results show that the phase shifter could achieve 13.6% impedance bandwidth with the reflection coefficient below -15dB. Meanwhile, the insertion losses of all output ports fluctuate around 6 +/- 0.5dB and the phase differences remain stably linear over the whole operational bandwidth.
