Abstract

Disclosed are a phase shifter and antenna. The phase shifter comprises an arc conductor component and a coupling arm component swingably disposed along the arc conductor component. The arc conductor component comprises: a first arc conductor and a second arc conductor concentrically disposed; the coupling arm component comprises: a first coupling arm and a second coupling arm disposed in a spatially isolated manner; a first end of the first coupling arm is in overlapping contact with the first arc conductor, and a second end of the first coupling arm is the input end of an input signal; a first end of the second coupling arm is in overlapping contact with the first arc conductor, and a second end of the second coupling arm is in overlapping contact with the second arc conductor; the first coupling arm and the second coupling arm are in overlapping contact with the first arc conductor at different locations, and a capacitive coupling electrical connection is formed at each overlapping contact between the coupling arms and the arc conductors. The phase shifter provided in the embodiments of the present invention is simple in structure and convenient for fabrication, able to effectively reduce the coupling between the arc conductors, thus improving the performance of the phase shifter.
