Problems solved by technology

[0003] In the prior art, the liquid crystal phase shifter is provided with support columns for supporting the cell thickness. However, based on the current location of the support columns, the cell thickness uniformity of the liquid crystal phase shifter is not high, resulting in the filling of liquid crystals in different regions. The volume difference is large, which affects the radiation angle of the RF signal radiated by the liquid crystal phase shifter, thereby affecting the antenna gain

Abstract

Embodiments of the present invention provide a phase shifter and a manufacturing method thereof, an antenna and a manufacturing method thereof, which relate to the technical field of electromagnetic waves, and effectively improve the cell thickness uniformity in the key region of the phase shifter for phase shifting radio frequency signals. The phase shifter includes: a first substrate and a second substrate arranged oppositely, a first electrode for receiving a ground signal is arranged on the first substrate, and a second electrode is arranged on the side of the second substrate facing the first substrate; liquid crystal, liquid crystal It is packaged between the first substrate and the second substrate, and the first electrode and the second electrode drive the liquid crystal to rotate; the support structure is arranged between the first substrate and the second substrate, and the support structure includes a first support column, and the first The support column is located on the side of the second electrode facing away from the second substrate, and the orthographic projection of the first support column on the second substrate is located within the orthographic projection of the second electrode on the second substrate.

Description

【Technical field】 [0001] The invention relates to the technical field of electromagnetic waves, in particular to a phase shifter and a manufacturing method thereof, an antenna and a manufacturing method thereof. 【Background technique】 [0002] With the gradual evolution of communication systems, phase shifters have become more and more widely used. Taking liquid crystal phase shifters as an example, liquid crystal phase shifters control the rotation of liquid crystals to change the dielectric constant of liquid crystals to achieve The radio frequency signal transmitted in the liquid crystal phase shifter is phase shifted. [0003] In the prior art, the liquid crystal phase shifter is provided with a support column for supporting the cell thickness. However, based on the current position of the support column, the cell thickness uniformity of the liquid crystal phase shifter is not high, resulting in the filling of liquid crystals in different regions. The volume difference ...
