Abstract
A substrate integrated waveguide (SIW) for phase shifter for millimeter wave applications has a waveguide with a plurality of curved sections and which passes through the substrate from a wave entry port to a wave exit port. The plurality of curved sections forms a serpentine path of curves in a first direction followed by curves in a second direction which are opposite the first direction. Phase shifting elements are positioned in the waveguide in each of the curved sections. The phase shifting elements may take the form of PIN diodes or a pattern of liquid metal filled vias in the waveguide.
