Description
Technical Field
The invention relates to the field of communication equipment, in particular to a metamaterial functional sheet, a metamaterial antenna panel and a metamaterial panel antenna.
Background
In the prior art, the field of metamaterial panel antennas mainly comprises main components such as a dielectric substrate 2', a first adhesive film 3', a back plate supporting layer 7', a metal reflecting layer 5', a second adhesive film 6', a light supporting layer 4', and the like, wherein a conductive geometric structure layer 1' is formed on the surface of the main components. Because the antenna panel has higher structural strength requirement, the antenna panel is generally pressed by adopting an integral glue-connection curing mode to form a dense and inseparable whole. The scheme is simple and easy to implement, has better strength and can meet most of requirements. However, the functional metamaterial layer (i.e. the conductive geometric structure layer) with key functions is located on the surface layer of the device, and the surface protection film is limited in thickness (less than 0.1 mm) and strength due to loss and thickness, so that damage or abrasion is easy to occur in a severe environment. Due to the integrated design of the whole antenna, when the metamaterial functional layer is damaged in a large scale, the whole antenna panel needs to be replaced. However, other parts of the antenna panel are relatively good in strength after being integrally pressed, and are generally not easy to damage, so that loss and material waste during replacement are relatively serious. The problem also represents a lack of serviceability design in the original design.
Fig. 1 shows a design framework of a conventional metamaterial panel antenna, wherein the whole antenna surface is composed of a conductive geometric structure layer 1', a dielectric substrate 2', a first adhesive film 3', a light substrate supporting layer 4', a metal reflecting layer 5', a second adhesive film 6', and a back plate bracket 7 'from top to bottom, wherein the geometric structure of the conductive geometric structure layer is attached to the surface of the dielectric substrate 2' through an etching process and cannot be separated. Under this framework, any damage will result in replacement of the entire panel. In the whole system, the conductive geometric structure layer 1' at the surface position is most easily damaged, and is extremely easy to scratch or collide. Although the protective film is added on the surface of the antenna, the protective film is very limited in thickness and strength due to performance, mainly plays roles of preventing water and scratch, and is insufficient in protection against direct physical injury. In addition, the dielectric substrate 2' must be integrally pressed with all the lower components during the processing, so that the overall strength requirement can be achieved, and it is difficult to separate the components for the design and process and then combine the components separately.

Detailed Description
It should be noted that, in the case of no conflict, the embodiments and features in the embodiments may be combined with each other. The invention will be described in detail below with reference to the drawings in connection with embodiments.
Technical terms:
the metamaterial refers to an artificial composite structure or a composite material which realizes the extraordinary physical properties which are not possessed by the material in the nature through a periodically and regularly arranged geometric structure. The metamaterial comprises a dielectric layer and a conductive geometry layer formed on a surface of the dielectric layer. And the conductive geometric structure layer consists of a plurality of conductive geometric structures which are regularly arranged according to the periodicity.
The conductive geometry is a planar or solid structure with a geometric figure made of conductive material. The conductive geometry may be a separate geometry formed of conductive material; the conductive material between adjacent hollow geometries can form a conductive geometry structure.
The electromagnetic property of the metamaterial is mainly determined by the shape, the size, the arrangement mode and other factors of the conductive geometric structure or the hollow geometric structure, and the required equivalent dielectric constant and magnetic permeability can be obtained by adjusting the shape, the size, the arrangement mode and other parameters of the conductive geometric structure or the hollow geometric structure, so that the metamaterial is widely applied to realizing refractive index change, electromagnetic stealth, perfect wave absorption, wave transmission performance improvement, polarization control and the like.
As shown in fig. 2, the metamaterial functional chip according to the embodiment of the present invention includes a sheet-shaped carrier layer 21, and a conductive geometry layer 22 is disposed on at least one surface of the sheet-shaped carrier layer 21, and the metamaterial functional chip is replaceably attached to the surface of the dielectric substrate.
When the metamaterial functional sheet is used as a traditional metamaterial functional layer (namely a conductive geometric structure layer), the metamaterial functional sheet is adhered to the surface of the medium substrate, and after the conductive geometric structure layer 22 is damaged, only the metamaterial functional sheet needs to be replaced, so that waste is reduced.
Preferably, the dielectric substrate has a dielectric constant similar to or the same as that of the sheet-like support layer 21. Preferably, the sheet-like carrier layer 21 is of a flexible material, such as paper or a dielectric film.
