Abstract

The invention discloses a phase shifter, which comprises a metal cavity body. The metal cavity body comprises an upper cover plate, a lower bottom plate and a lateral plate, the inside of the metal cavity body is divided into pluralities of cavities through partition boards, two parallel metal conductive cylinders and a U-shaped metal conductor are arranged inside each cavity of the metal cavity body, two free ends of one U-shaped metal conductor are respectively inserted into the two metal conductive cylinders; the U-shaped metal conductor is connected with an insulating pull rod which is positioned via an insulation guide part, the insulation pull rod drives each U-shaped metal conductor to move leftwards and rightwards correspondingly to the metal conductive cylinders; the insulation guide part is fixedly connected with the metal cavity body; the two metal guide cylinders are respectively connected with coaxial cables. The phase shifter enables phase control of each radiation unit to be extremely convenient, and has simple structure and low cost.

Description

technical field

[0001] The invention relates to an antenna component, in particular to a phase shifter for a base station antenna. Background technique

[0002] In addition to the radiation unit, reflector, and feed network, the phase shifter is an important part of the phased antenna. The phase shifter is mainly used in the base station antenna to adjust the phase change of the feed network, so as to change the phase of each or a group of radiating elements, and achieve the purpose of changing the vertical beam inclination or horizontal beam angle, which is a wireless network. Operators provide more flexible optimization means to optimize the performance of the entire system.

[0003] U.S. Patents US7463190 and US6850130 respectively disclose an integrated phase shifter with one input terminal and multiple output terminals. These two phase shifters all use a moving mechanism to achieve the phase change of multiple output terminals. These output terminals are connected thro...
