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

The embodiment of the invention provides a phase shifter, a manufacturing method of the phase shifter, an antenna and a manufacturing method of the antenna, relates to the technical field of electromagnetic waves, and effectively improves the box thickness uniformity in a key area for performing phase shifting on a radio frequency signal in the phase shifter. The phase shifter comprises a first substrate, a second substrate, liquid crystal and a supporting structure, wherein the first substrate and the second substrate are oppositely arranged, the first substrate is provided with a first electrode used for receiving a grounding signal, and the side, which faces the first substrate, of the second substrate is provided with a second electrode; the liquid crystal is packaged between the first substrate and the second substrate, and the first electrode and the second electrode drive the liquid crystal to rotate; and the supporting structure is arranged between the first substrate and the second substrate, the supporting structure comprises a first supporting column, the first supporting column is located on the side, which is opposite to the second substrate, of the second electrode, and the orthographic projection of the first supporting column on the second substrate is located in 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 the communication system, the phase shifter has been more and more widely used. Taking the liquid crystal phase shifter as an example, the liquid crystal phase shifter changes the dielectric constant of the liquid crystal by controlling the rotation of the liquid crystal, so as to realize the The RF signal transmitted in the liquid crystal phase shifter is phase shifted. [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 ...
