Embodiment Construction

[0032] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0033] The existing methods for increasing the phase shifting amount of the dielectric phase shifter mainly include increasing the physical stroke and increasing the dielectric constant of the sliding medium. However, increasing the physical stroke will result in an increase in the size of the phase shifter unit, which in turn leads to an increase...

Abstract

An embodiment of the present invention provides a phase shifter, a phase shifter, and a base station antenna, wherein the phase shifter includes a sliding medium and a plurality of strip lines; each of the strip lines includes a main transmission line and several loads arranged on the main transmission line part; each of the strip lines is connected by the main transmission line; at least one of the main transmission line parameters and / or loading section parameters of two adjacent sections of the strip line is different from each other; the sliding medium is used for passing Sliding changes the coverage state on the multi-segment strip lines, thereby realizing phase shifting. The phase shifting unit, the phase shifter and the base station antenna provided by the embodiments of the present invention, by setting multi-segment strip lines, make the sliding medium change the coverage state of the multi-segment strip lines during the sliding process, thus without increasing the size of the phase shifting unit , combining the phase shifting section and the matching section into one, which increases the amount of phase shifting, reduces the number of matching stages, improves the matching effect, and solves the problem that the electric adjustment base station antenna requires a large amount of phase shifting.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular, to a phase shift unit, a phase shifter, and a base station antenna. Background technique [0002] In the mobile communication network coverage, the base station antenna is one of the key equipment of the coverage network, and the phase shifter is the core component of the electric adjustment base station antenna. The performance of the phase shifter directly determines the performance of the electric adjustment base station antenna, and then affect the coverage quality of the network. [0003] The dielectric phase shifter mainly adjusts the phase size from the input port to the output port by moving the medium in its cavity to change the phase input to the antenna array, thereby adjusting the beam downtilt angle of the base station antenna. Currently, dielectric phase shifters are widely used in the industry. However, the phase shift amount of...
