Abstract

The present disclosure provides a phase shifting apparatus and an electrically adjustable antenna. The phase shifting apparatus comprises a grounding plate; two bottom substrates respectively arranged on both sides of the grounding plate and coupled to the grounding plate; two top substrates respectively arranged on both sides of the two bottom substrates, wherein each of the top substrates and each of the bottom substrates form a phase shifting unit; a rod coupled to the two top substrates for adjusting a relative sliding movement between the two top substrates and the two bottom substrates so as to simultaneously adjust a phase of the output signal of each phase shifting unit. By employing the technical solution of the present disclosure, screws are not needed in course of assembling the phase shifting apparatus, PIM performance of the phase shifting apparatus is improved, and the friction force is smaller so that an ACU can drive the rod at a low temperature. The phase shifting apparatus has fewer parts and is low cost, meanwhile the parts are connected using nonmetallic rivets for ease of assembling and reworking.
