Embodiment 1

[0042] like figure 1 As shown in a liquid crystal laminate antenna includes an upper electrode substrate 11, the intermediate electrode substrate 12 and the lower electrode substrate 13, the upper electrode substrate 11, the intermediate electrode substrate 12 and the lower electrode substrate 13 is provided the use of superimposed sequentially, three electrode substrate materials include but not limited to plate glass material, a quartz material plate, ceramic plate, a silicon wafer, and the PCB material sheet other polymeric materials such as PET, PI, LCP plate, the electrode substrate may also be employed in some of the leading edge of a flexible product substrate, such as PET, PMMA, PI, and the flexible web material glass substrate, in this document to use glass material as an example.

[0043] In the choice of the thickness of the upper electrode substrate 11, the substrate thickness of the intermediate electrode 12 and the lower electrode substrate 13 are between 0.1-2.0 mm,...

Embodiment 2

[0074] According to the second embodiment differs from that of Embodiment 1 only: The image 3 , Figure 5 , The thickness of the spacer comprises PS (PostSpacer, post spacer) 22 and a column filled with the liquid crystal and a liquid crystal dropwise addition packaged using laminated (ODF) technique.

[0075] When using a liquid crystal dropping lamination (ODF) liquid crystal filling and packaging technology, the need to first upper electrode substrate 11, the lower substrate 13 to complete the front electrode pattern producing PS post 22, the upper electrode film 13 and the lower electrode substrate 11 in the substrate a front coating layer where the thickness of the positive photoresist 2um, at a temperature of 105 ℃ soft bake for 5 minutes. After cooling into the lithography exposure, exposure time 8 seconds, then put in a developing step for developing, water washing after the completion of drying, 150 deg.] C and then hardened for 10 minutes to obtain a highly 8um PS post 22...

Abstract

The invention relates to a laminated liquid crystal antenna and a manufacturing method thereof, the laminated liquid crystal antenna comprises an upper electrode substrate and a lower electrode substrate, a middle electrode substrate is arranged between the upper electrode substrate and the lower electrode substrate, an upper liquid crystal layer is filled between the upper electrode substrate and the middle electrode substrate, a lower liquid crystal layer is filled between the lower electrode substrate and the middle electrode substrate, and electric field forces for deflecting liquid crystal molecules of the upper liquid crystal layer and the lower liquid crystal layer are respectively formed between two sides of the middle electrode substrate and the adjacent upper electrode substrate and the lower electrode substrate. The middle electrode substrate is introduced between the upper electrode substrate and the lower electrode substrate to serve as a supporting substrate of the laminated liquid crystal antenna, the transmission loss of radio-frequency signals can be effectively reduced, the thickness of the antenna is controlled, and the requirement of an ultrathin light antenna is met.

Description

Technical field [0001] The present invention relates to the field of wireless communications, particularly to a liquid crystal laminate antenna manufacturing method thereof. Background technique [0002] Based on the good RF performance of the liquid crystal (LC) material and a liquid crystal array antenna phased array antenna, the art is a new product and engineering academic focus in recent years. The liquid crystal belonging to electronic scanning antenna (ESA) tunable phased array antenna is an important branch, and can be widely used in the millimeter wave frequency microwave antenna products. Compared to traditional mechanical antenna, the antenna having a fast response liquid crystal, compact size, easy operation and maintenance and other significant advantages, and with the realization of large-scale production, the cost will be greatly reduced. It is possible to satisfy things, 5G and satellite communication services such as wireless Internet communications technology fo...
