Embodiment Construction

[0026] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0027] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes ...

Abstract

The invention relates to a phase shifter unit, a phase shifter and an antenna. The phase shifter unit includes a dielectric substrate and a movable circuit. The dielectric base material includes a plate body and a limiting member. The limiting member cooperates with the plate body to form a slideway, and metal circuits are formed on the side of the plate body and the limiting member facing the slideway to form a fixed circuit layer. The movable circuit is installed in the slideway, and the limit is realized by the cooperation of the plate body and the limit piece. The slideway can play a good role in limiting and guiding the movable circuit, so the sliding stability of the movable circuit is better and it is not easy to fluctuate. Furthermore, metal circuits are formed on both the plate body and the limiting member, so the obtained fixed circuit layer is a three-dimensional structure rather than a single-sided structure. Therefore, the fixed line layer and the movable line layer are multi-faceted coupling, and the coupling effect between the two is strengthened. Even if there are fluctuations in the sliding process of the movable circuit, the coupling connection can be kept stable. It can be seen that the stability of the phase shifter unit and the phase shifter is significantly improved.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a phase shifter unit, a phase shifter and an antenna. Background technique [0002] In the coverage of mobile communication network, the electric adjustable base station antenna is one of the key equipment of the coverage network, and the phase shifter is the core component of the electric adjustable base station antenna. Existing phase shifters mainly implement phase shifting in two ways, including a dielectric sliding type and a conductor sliding type. [0003] The conductor sliding phase shifter changes the electrical length of the phase shifter by moving the conductor to achieve the purpose of phase change. Generally, it includes a fixed circuit and a movable coupling circuit, and the coupling circuit is pressed against the fixed circuit by plastic parts. However, there may be undulations in the sliding process of the coupling circuit, resulting in a gap with...
