Phase shifter of antenna device

Abstract

The present disclosure relates to a phase shifter for antenna apparatuses. Particularly, the phase shifter includes a dielectric panel for phase adjustment (hereinafter referred to as “phase dielectric”) movably disposed at a branch point of a transmission line disposed to be spaced apart from one surface of a reflecting panel, a dielectric panel for impedance matching (hereinafter referred to as “impedance dielectric”) fixedly disposed parallel to one side of the phase dielectric, and a moving clamp configured to move the phase dielectric. The phase dielectric has an impedance matching step stepped such that an air layer is formed on a surface facing the reflecting panel, thereby providing an advantage of preventing the exterior of the transmission line from being complicated.
