Abstract

The invention provides a manufacturing method of an artificial dielectric multilayer cylindrical lens. A granular material with a high dielectric constant epsilon (1.0<epsilon< / =3.0) is adhered to a single-sided adhesive foam substrate with a low dielectric constant (1.0<epsilon<2.0), a width (10 mm<H<10000 mm) and a thickness (0<t<10 mm); and rolling or pressing into an n-layer (1< / =n< / =1000) cylinder and elliptic cylinder with a height of H (10 mm<H<10000 mm) and the diameter of D is then carried out; and the epsilon of each layer is the same, different or gradually reduced (2.0> / =epsilon>1.0). The cylindrical lens manufactured through the method is ultra-light in weight, ultra-wide in frequency, capable of meeting the application requirements of various antennas, simple and feasible inmanufacturing process, high in quality consistency, low in manufacturing cost, particularly suitable for batch production, and particularly suitable for mobile communication 5G, 4G, MIMO and even millimeter wave base station antennas.

Description

technical field [0001] The invention relates to the technical field of antenna engineering, in particular to a method for manufacturing an artificial dielectric multilayer lenticular lens. Background technique [0002] With the application of Lunberg dielectric lens antenna in the field of mobile communication, higher requirements are put forward for the manufacturing method of Lunberg dielectric lens. While maintaining the high gain, wide beam, and ultra-light performance of the original dielectric lens antenna, it is also required that the manufacturing process of the dielectric lens be simpler, the operability is stronger, the one-time yield is higher, and it is more suitable for mass production. [0003] The traditional Lumber ball antenna is mainly made by two processes of punching and foaming. The process is time-consuming and cumbersome and the product quality is too heavy. The efficiency of the lens antenna is very low; the dielectric constant of the material obtain...
