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 relevant drawings. The drawings show preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is 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 may be directly on the other element or a central element may also exist. When an element is considered to be "connected" to another element, it can be directly connected to the other element or an intermediate element may be present at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustr...

Abstract

The invention relates to a phase shifter unit, a phase shifter and an antenna. The phase shifter unit comprises a dielectric substrate and a movable circuit. The dielectric substrate comprises a platebody and a limiting piece, wherein the limiting piece is matched with the plate body to form a slide way, and metal circuits are formed on the sides, facing the slide way, of the plate body and the limiting piece to form a fixed circuit layer. The movable circuit is arranged in the slide way in a penetrating mode and is limited through cooperation of the plate body and the limiting piece. The slide way can play a good role in limiting and guiding the movable circuit, so that the sliding stability of the movable circuit is better, and fluctuation is not prone to occurring. Furthermore, the metal circuits are formed on the plate body and the limiting piece, so that the obtained fixed circuit layer is of a three-dimensional structure instead of a single-sided structure; the fixed circuit layer and the movable circuit layer are in multi-surface coupling, and the coupling effect between the fixed circuit layer and the movable circuit layer is enhanced; even if fluctuation exists in the sliding process of the movable circuit, coupling connection can be kept stable; and therefore, the stability of the phase shifter unit and the phase shifter is remarkably improved.

Description

Technical field [0001] The present 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 networks, the ESC base station antenna is one of the key equipment of the coverage network, and the phase shifter is the core component of the ESC base station antenna. The existing phase shifters mainly implement phase shifting through two methods 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 contains a fixed circuit and a movable coupling circuit, and the coupling circuit is pressed against the fixed circuit by a plastic part. However, there may be fluctuations in the sliding process of the coupling circuit, resulting in a gap with the fixed circui...
