Embodiment Construction

[0031] 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. Rather, these embodiments are provided for the purpose of making the disclosure of the present invention more thorough and comprehensive.

[0032] 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 of illustrat...

Abstract

The invention relates to a medium mobile phase shifter and a base station antenna. When a coupling circuit overlaps with a transmission line breakpoint, both ends of the transmission line breakpoint are connected by the coupling circuit, and multiple output ports are connected to an input port, thus achieving signal output. When the coupling circuit is staggered from the transmission line breakpoint, the coupling of transmission line breakpoint is broken, at least part of the output ports are disconnected from the input port, and the number of output ports for signal output is reduced. The more output ports participating in the signal output are, the more antenna oscillators playing a role in the signal output are, and the narrower the beam is. Otherwise, the wider the beam is. Then, the electrical length of a travel line in a power dividing phase shifting circuit can be adjusted by moving a phase-shifting medium plate, which changes the output phase of each output port. It can be seenthat the above-mentioned medium mobile phase shifter can not only adjust the lower inclination of the beam, but also switch between the wide beam and the narrow beam by moving a coupling unit. Therefore, the application scenario of the above medium mobile phase shifter and base station antenna has been effectively widened.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a medium mobile phase shifter and a base station antenna. Background technique [0002] In the signal coverage process of mobile communication, the electric adjustable antenna is very well adapted to the needs of the industry with its flexible beam adjustment and remote control functions, and is very popular in the field of mobile communication. In recent years, with the in-depth development of mobile communications, the requirements for miniaturization, integration, high performance, and low cost of electronically adjustable antennas have increased the requirements for its core component, the phase shifter. [0003] Phase shifters in mobile communications are generally classified into network sliding type and medium sliding type. The network sliding phase shifter changes the phase by changing the physical length of the transmission path, but this type of phase sh...
