Problems solved by technology

This solution avoids the overall surface treatment of the cavity, and the cost is low, but because its electrical connection involves the stable state of the interconnection among the cavity, the metal ground block, and the metal screw, these connections will produce nonlinear contact, which will It will lead to the increase and instability of the antenna passive intermodulation (passiveInter-Modulation, abbreviation: PIM) value and standing wave ratio

Abstract

A phase shifter relates to the field of antenna manufacturing. The phase shifter comprises a phase shifter cavity, a feeding network assembly, a feeding seat and a coaxial cable, wherein the feeding network assembly is arranged in the phase shifter cavity, the feeding seat is arranged at an outer side of the phase shifter cavity, an inner core of the coaxial cable is electrically connected with the feeding network assembly, an external conductor of the coaxial cable is electrically connected with the feeding seat, and the feeding seat is arranged at the outer side of the phase shifter cavity in an insulation way so that a coupling feeding space is formed between the feeding seat and the phase shifter cavity. The feeding seat and the phase shifter cavity are maintained to be completely insulated, the coupling feeding space between the feeding seat and the phase shifter is formed, and the electrical function is achieved by coupling feeding between the feeding seat and the phase shifter cavity; and by the scheme, the cost is reduced, a PIM value of an antenna is reduced, and the index stability of the PIM value and standing-wave ratio are improved.

Description

technical field [0001] The invention relates to the field of antenna manufacturing, in particular to a phase shifter applied to antennas. Background technique [0002] In the prior art, the dielectric phase shifter in the antenna is mainly divided into two structural forms: [0003] 1. The cavity of the phase shifter is designed in one piece, the surface of the cavity is treated as a whole, and the outer conductor of the feeder is welded on the outer surface of the cavity to realize electrical connection. The structure of this scheme is simple, but the cavity needs to be treated on the whole surface, and the cost is high. [0004] 2. The welding part of the phase shifter and the outer conductor of the feeder is designed separately, and the metal grounding block is designed. The outer conductor of the feeder is welded to the metal grounding block, and the metal grounding block is fastened to the cavity by screws to realize electrical connection. This solution avoids the ov...
