Embodiment Construction

[0018] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the embodiments and accompanying drawings.

[0019] figure 2 Shown is a schematic cross-sectional structure diagram of the hemispherical multilayer dielectric lens of the present invention. Such as figure 2 As shown, the hemispherical multilayer dielectric lens is a hollow hemisphere. The hollow hemisphere is a special hemisphere formed by hollowing out the center of the hemisphere. The hollowed out part forms a hollow area 4 , and the hollow area 4 of the multilayer dielectric lens can be used to place the antenna array 5 . The hemispherical multilayer dielectric lens includes multilayer dielectrics. The hemispherical multilayer dielectric lens consists of a low dielectric constant dielectric layer 1 , a medium dielectric constant dielectric layer 2 and a high dielectric constant dielec...

Abstract

The invention relates to the technical field of wireless communication, and provides a hemispherical multilayer dielectric lens, an antenna module, a high-frequency wireless module and equipment. According to the invention, gradient change of dielectric constants of different dielectric layers in the hemispherical multilayer dielectric lens is utilized; high-frequency electromagnetic waves pass through the multilayer dielectric lens. According to the invention, a high-focusing directional radiation wave beam is formed, the radiation characteristic of a millimeter wave or terahertz active module can be remarkably improved, the effective radiation power of a high-frequency wireless signal can be improved on the premise of reducing the number of array antenna units, the requirement on the output power of the active module is reduced, and the wave beam scanning range is expanded. Meanwhile, the multilayer dielectric stack is low in cost and easy to be integrated with an active module. Themethod is very suitable for a millimeter wave radar system and a terahertz high-resolution imaging system.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a hemispherical multilayer dielectric lens, an antenna module, a high-frequency wireless module and equipment. Background technique [0002] Existing multilayer dielectric lenses such as figure 1 As shown, it usually includes a low-k dielectric layer, a medium-k dielectric layer and a high-k dielectric layer. Since most of the current large array antenna module structures use microstrip patch antenna arrays to achieve gain combining and beam scanning, it is necessary to increase the number of antenna elements to form a large array to obtain high gain and high directivity, and large array antennas will occupy Larger area will limit the range of scan angle at the same time. Contents of the invention [0003] (1) Solved technical problems [0004] The main purpose of the present invention is to provide a hemispherical multi-layer dielectric lens, antenna module, ...
