Abstract

Embodiments of the present application provide a liquid crystal phase shifter and electronic equipment, which relate to the field of signal transmission and are used to solve the problem that part of the electric field in the liquid crystal phase shifter does not enter the liquid crystal layer. The liquid crystal phase shifter includes a liquid crystal cell and an intermediate substrate horizontally arranged in the middle of the liquid crystal cell. The liquid crystal phase shifter also includes a first microstrip line and a second microstrip line respectively located on opposite sides of the middle substrate. The above-mentioned liquid crystal phase shifter is used to adjust the phase of the microwave signal input into the first microstrip line and the second microstrip line.

Description

technical field [0001] The invention relates to the field of signal transmission, in particular to a liquid crystal phase shifter and electronic equipment. Background technique [0002] A phase shifter is a device that can adjust the phase of a wave, and it has a wide range of applications in the fields of radar, missile attitude control, accelerator, communication, and instrumentation. At present, the commonly used phase shifters mainly include varactor diode phase shifters, ferrite phase shifters, PIN diode phase shifters, MEMS (Micro-Electro-Mechanical System, micro-electro-mechanical system) phase shifters, and liquid crystal phase shifters. Wait. [0003] Among them, for the liquid crystal phase shifter, the dielectric constant of the liquid crystal layer can be controlled by applying a voltage, so with the difference of the applied bias voltage, the above dielectric constant can be continuously changed, and then continuous phase shift adjustment can be realized. Howe...
