Embodiment Construction

[0025] 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.

[0026] The broadband phase shifter provided by the embodiment of the present invention is a phase shifter designed based on a microstrip line. In the traditional phase shifter design idea, one branch is a 50Ω uniform transmission line, and the other branch has a nonlinear phase. By changing If the length of the uniform transmission line is 50Ω, a ...

Abstract

The embodiment of the invention provides a broadband phase shifter and a broadband wave beam nature network. The broadband phase shifter comprises a dielectric material plate, a floor and a microstrip transmission line. The floor and the microstrip transmission line are respectively arranged on the two sides of the dielectric material plate. The floor is in ground connection. The two ends of the dielectric material plate are respectively the input port and the output port of the broadband phase shifter. At least one open circuit knob or short circuit knob are arranged on the microstrip transmission line. The broadband phase shifter and the broadband wave beam nature network provided by the embodiment of the invention are used for broadband of the phase shifter and broadband of the wave beam nature network.

Description

technical field [0001] The embodiment of the present invention relates to wireless communication technology, and in particular to a broadband phase shifter and a broadband beam-forming network. Background technique [0002] With the development of wireless communication technology, wireless communication devices need to transmit more and more data, so the wireless communication devices need to work in a wider bandwidth, and correspondingly, the antennas of the wireless communication devices also need to support wider bandwidths. [0003] In prior art wireless communication devices such as base stations, multi-beam shaped feeding networks are used to feed antennas, and multi-beam shaped feeding networks are composed of phase shifters and hybrid orthogonal networks. The phase shifter in the multi-beam adaptive feeding network in the prior art is a narrow-frequency phase shifter, which causes the multi-beam adaptive feeding network to exhibit narrow-band characteristics, so tha...
