Problems solved by technology

[0004] It is known that the existing phased array antenna has this performance index, but it is based on the application background of the national defense field and the chip manufacturing process. Its expensive production cost and high power consumption make it unaffordable for consumers in the consumer market, thus causing obstacles to the popularization of consumer products.
[0005] The traditional mechanically rotating parabolic antenna has the problems of large size, heavy, easy to damage, and high cost, and it is difficult to meet the needs of new applications such as vehicles / aircrafts

Abstract

The invention discloses a method for manufacturing a flat-panel liquid crystal antenna. The method comprises steps of: providing a first substrate, wherein the two sides of the first substrate are provided with a first metal film layer and a third metal film layer respectively; patterning the double metal film layers simultaneously to obtain a patterned first metal film layer and a patterned thirdmetal film layer; providing a second substrate having a second metal film layer at one side; patterning the second metal film layer to obtain a patterned second metal film layer; combining the firstsubstrate and the second substrate to form a liquid crystal cell, and preparing a liquid crystal layer. The present invention also discloses a flat-panel liquid crystal antenna manufactured by the method. By means of structural improvement, the method makes it possible to simultaneously pattern the double-sided metal, removes inefficient yellow light process steps, and saves busy waiting time andmodel switching tuning time. The flat-panel liquid crystal antennas can be manufactured on a large scale, which improves the manufacturing efficiency and reduces the manufacturing cost.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a flat liquid crystal antenna and a manufacturing method thereof. Background technique [0002] The development of information networks is changing with each passing day, and major changes are being or will be produced in various fields, among which hot technologies include 5G and satellite mobile Internet communication technology.
