Title: SUPER WIDE BAND PHASE SHIFTER
Abstract:
Provided is a super wide band phase shifter, comprising a cavity (10) and a cover plate (20) covering on the cavity, and further comprising: a first phase shift mainboard (31) and a second phase shift mainboard (32) that are polarized and coincided, a first coupling arm (41) and a second coupling arm (42) that are rotatably fixed on the cavity (10). The first phase shift mainboard and the second phase shift mainboard both have a shaft hole (34) and a plurality of arc conductors (36) arranged on the periphery of the shaft hole (34) in sequence. The first coupling arm and the second coupling arm both comprise a plurality of coupling conductors (44). The coupling conductors of the first coupling arm (41) and the arc conductors of the phase shift mainboard (31) form a capacitive coupling. The coupling conductors of the second coupling arm (42) and the arc conductors of the second phase shift mainboard (32) constitute the capacitive coupling. The present invention is capable of increasing the amount of phase shift, reducing the size of the phase shifter, and achieving multi-branched ultra-wideband.
