Title: MINIATURISED SINGLE-STEP PHASE SHIFTER
Abstract:
The present invention relates to a miniaturised single-step phase shifter comprising a lower grounding plate, an upper grounding plate installed on the lower grounding plate, and a first phase-shifting power-splitting network and a second phase-shifting power-splitting network located between the lower grounding plate and the upper grounding plate, wherein the first and second phase-shifting power-splitting networks are provided in a staggered manner along the longitudinal direction of the lower grounding plate and are arranged along the transverse direction of the lower grounding plate; the first phase-shifting power-splitting network comprises a first metal strip-shaped wire and a first dielectric sliding block installed on the lower grounding plate, and the first dielectric sliding block is provided on the first metal strip-shaped wire and can slide along the transverse direction of the first metal strip-shaped wire; the second phase-shifting power-splitting network comprises a second metal strip-shaped wire and a second dielectric sliding block installed on the lower grounding plate, and the second dielectric sliding block is provided on the second metal strip-shaped wire and can slide along the transverse direction of the second metal strip-shaped wire; and the first and second dielectric sliding blocks are mutually staggered along the longitudinal direction of the lower grounding plate. The present invention has a compact structure, is small in volume, and is light in weight, and has good amplitude and phase characteristics.
