Miniaturized dielectric phase shifter based on gradual change hole

The utility model relates to a miniaturized dielectric phase shifter based on gradual change hole, including box body, apron, transmission line, dielectric block and slide mechanism, the box body is one end open -ended cavity rectangle piece, opening part at the box body is furnished with the apron, the outside at the apron is equipped with slide mechanism and slide hole, be equipped with transmission line and dielectric block in the cavity of box body, wherein, transmission line and box body inner wall are insulating to be connected, and dielectric block passes behind the slide hole on the apron and to be connected with the slide mechanism in the outside, it has the side recess to open in the dielectric block's adjacent with the transmission line side, dielectric block's side recess is passed at the middle part of transmission line, transmission line and dielectric block contactless, profitable technological effect: the utility model discloses a biggest advantage is small, and during the antenna was transferred to the limited basic station in specially adapted space electricity, in addition moved looks ware simple structure, easy manufacturing, and have that phase continuation changes, the intermodulation characteristic is good, move phasor characteristics greatly concurrently.
