Abstract

An embodiment of the invention provides a liquid crystal phase shifter and an antenna, and relates to the technical field of electromagnetic waves. The liquid crystal phase shifter has a deformable feature, and can be applied to extensive scenes. The liquid crystal phase shifter comprises a first substrate, a second substrate, a liquid crystal layer and at least one phase shifting unit. The firstsubstrate is opposite to the second substrate. The liquid crystal layer is located between the first substrate and the second substrate. The first substrate comprises a first flexible substrate and afirst liquid crystal alignment layer. The first liquid crystal alignment layer is located on one side, close to the second substrate, of the first flexible substrate. The second substrate comprises asecond flexible substrate and a second liquid crystal alignment layer. The second liquid crystal alignment layer is located on one side, close to the first substrate, of the second flexible substrate.Each phase shifting unit comprises a microstrip line and a phase control electrode. The microstrip lines are located between the first flexible substrate and the first liquid crystal alignment layer.The phase control electrodes are located between the second flexible substrate and the second liquid crystal alignment layer.

Description

【Technical field】 [0001] The invention relates to the technical field of electromagnetic waves, in particular to a liquid crystal phase shifter and an antenna. 【Background technique】 [0002] A phase shifter is a device that can adjust the phase of electromagnetic waves. It is widely used in radar, missile attitude control, accelerator, communication, instrumentation, and even music. [0003] With the development of technology, a new liquid crystal phase shifter has appeared, but the current design of liquid crystal phase shifter, the liquid crystal cell is usually made of a rigid substrate, so that the liquid crystal phase shifter has a higher hardness, so that its application range restricted. 【Content of invention】 [0004] In view of this, an embodiment of the present invention provides a liquid crystal phase shifter and an antenna, which can make the liquid crystal phase shifter have a deformable characteristic and be applicable to a wider range of scenarios.
