Description

technical field [0001] The present application relates to the technical field of wireless communication, in particular to a liquid crystal antenna panel and a manufacturing process thereof. Background technique [0002] The liquid crystal antenna and its array phased array antenna based on liquid crystal (LC) material with good radio frequency performance are new products in the hot technical field of academia and engineering circles in recent years. Liquid crystal antenna is an important branch of electronically scanned (ESA) tunable phased array antenna, which can be widely used in millimeter wave and high frequency microwave antenna products. [0003] At present, the main technical solutions for liquid crystal antenna panels rely on traditional liquid crystal display panel production lines for production and manufacturing. However, the technology of the liquid crystal antenna panel needs to upgrade and transform the equipment of the traditional liquid crystal production ...
