Problems solved by technology

[0004] However, for liquid crystal phase shifters, loss has always been an obstacle to its application in phase shifters, and although liquid crystal phase shifters have the characteristics of high phase shift, their response time has always been limited; the size of ferroelectric phase shifters is small , the process is simple and the cost is low, but the problem of low phase shift limits its development

Abstract

The invention provides a phase shifter, a manufacturing method and working method thereof and belongs to the phase shifter technical field. The phase shifter includes a first sub-phase shifter and a second sub-phase shifter which are disposed in a stacked manner; the first sub-phase shifter and the second sub-phase shifter share the same microstrip line; and the microstrip line is located betweenthe first sub-phase shifter and the second sub-phase shifter. With the technical schemes of the present invention adopted, the response time of the phase shifter can be reduced, and the phase shiftingdegree of the phase shifter can be increased.

Description

technical field [0001] The invention relates to the technical field of phase shifters, in particular to a phase shifter and a manufacturing method and working method thereof. Background technique [0002] A phase shifter is a device that can adjust the phase of a wave, and has a wide range of applications in radar, missile attitude control, accelerators, communications, instrumentation, and even music. At present, the vast majority of phase shifters on the market are ferrite phase shifters and PIN diode phase shifters. However, ferrite phase shifters have the disadvantages of large size and slow response speed, and are not suitable for high-speed beam scanning; the disadvantages of diode phase shifters are large power consumption (requires a special cooling system), small power capacity and insertion loss It is not suitable for use as a light and low power phased array system. Recently, researchers found that using the anisotropy of the dielectric constant of liquid crysta...
