Problems solved by technology

[0005] Applying sealant multiple times on the peripheral area of ​​the first substrate will easily lead to the problem of glue collapse on the first substrate (that is, the phenomenon that the sealant flows in the surface of the first substrate), and it is difficult to maintain the relationship between the first substrate and the second substrate. Therefore, the adjustment range of the resonant frequency of the antenna unit is small, resulting in a small adjustment range of the resonant frequency of the liquid crystal antenna

Embodiment Construction

[0051] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0052]The liquid crystal antenna usually includes multiple antenna units. In order to enable the liquid crystal to deflect at different angles and adjust the resonant frequency of the liquid crystal antenna in a wide range, a sufficient gap needs to be maintained between the first substrate and the second substrate of the antenna unit. . Since the amount of sealant applied once on the peripheral area of ​​the first substrate is limited,...

Abstract

The invention discloses an antenna unit and a manufacturing method thereof, a liquid crystal antenna and communication equipment, and belongs to the technical field of antennas. The antenna unit comprises a first substrate and a second substrate opposite to each other, as well as a liquid crystal and a frame sealing structure between the first substrate and the second substrate, wherein a patch electrode is arranged on one side of the first substrate near the liquid crystal, a ground electrode is arranged on one side of the second substrate near the liquid crystal, and the frame sealing structure comprises a support and a sealant arranged on at least one side of the support. The antenna unit solves the problem that the adjustment range of the resonant frequency of the liquid crystal antenna is small, and helps to improve the adjustment range of the resonant frequency of the liquid crystal antenna. The antenna unit is applied to the liquid crystal antenna.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to an antenna unit and a manufacturing method thereof, a liquid crystal antenna, and communication equipment. Background technique [0002] The liquid crystal antenna is a micro-antenna that uses liquid crystal deflection to adjust the resonant frequency. The liquid crystal antenna usually includes a plurality of antenna units, and each antenna unit includes a first substrate and a second substrate oppositely arranged, and a liquid crystal and a sealant between the first substrate and the second substrate, and the first substrate is close to a side of the liquid crystal. The second substrate is provided with a patch electrode on the side close to the liquid crystal. The orthographic projection of the sealant on the first substrate is located in the peripheral area of ​​the first substrate. The liquid crystal is located in the space surrounded by the sealant. When a voltage is appl...
