Embodiment Construction

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0029] In view of the lack of a phase shifter with filtering function in current electronically modulated antennas, the present invention proposes to incorporate the function of the filter into the phase shifter to achieve the functions of phase shifting and filtering at the same time. Specifically, the traditional base station antenna signal first passes through a separate filter, and then enters the phase shifter; and the embodiment of th...

Abstract

Provided are a phase shifter with a filter element, a filter element and an antenna. The phase shifter comprises: a swing arm and an arc arm; a phase shift coupling ring arranged on the swing arm; a filter coupling ring concentrically coupled with the phase shift coupling ring; and a filter circuit board integrated with the filter coupling ring in one piece. Therefore, the embodiments of the present invention can provide a phase shifter with a filter function. In addition, the phase shifter integrated with the filter function is simple in structural design, so that components are saved, thereby being beneficial for reducing product costs.

Description

Technical field [0001] The present invention relates to the field of antennas, and in particular to a phase shifter with filter elements, filter elements and antennas that can be applied to antennas. Background technique [0002] In a mobile communication system, due to the needs of network coverage or network optimization, the beam pointing of the elevation plane of the base station antenna needs to be adjusted. For example, the adjustment of the elevation plane beam through the adjustable phase shifter works by changing the phase distribution of each radiating element of the array antenna, and then adjusting the downward tilt angle of the antenna beam. In this way, not only can the continuous adjustment of the main beam pointing be achieved, but also the horizontal plane beam can be guaranteed not to be deformed. [0003] Adjustable phase shifters are mainly divided into two types: medium phase shift and physical phase shift. Among them, the medium phase shift is realized by ch...
