Multibranched division phase shifter

摘要

Provided is a multibranched division phase shifter the structure of which is simple, the area of which is small, and the cost of which is low. The multibranched division phase shifter comprises first to nth output side strip conductors, which are formed on a dielectric substrate, which have arc shapes constituting portions of first to nth circular rings, respectively when the first to nth (n≥2) circular rings coaxially arranged to be in the shape of circles with a given point in the center are supposed, and both ends of which are output ends, an input side strip conductor which is formed on the dielectric substrate and one end of which ispositioned on the center of the circular ring, first to nth sliding sections which have arch shapes constituting portions of the first to nth circular rings, respectively and the lengths of which are shorter than that of the output side strip conductor, and an arm section which has the first to nth sliding sections and can rotate around the center of the circular ring. An insulator is interposed between the first to nth output side strip conductors and the first to nth arc-shaped oscillation sections and between the input side strip conductor and the arm section.
