Embodiment 1

[0021] see figure 2 , which is a flowchart of a method for preparing a dielectric substrate provided in Embodiment 1 of the present invention, the method includes the following steps:

[0022] S201: Using a material with a first dielectric constant as a substrate, coating a material with a second dielectric constant on a first position of the substrate.

[0023] For example, a polymer material with a first dielectric constant is used as a substrate, and a material with a dielectric constant greater than the first dielectric constant is coated on the substrate. The material with a dielectric constant greater than the first dielectric constant may be ceramics, mica, glass, plastic, or metal oxide.

[0024] S202: On the first position coated with the material with the second dielectric constant and the second position of the substrate, coat the material with the second dielectric constant to obtain a dielectric substrate with a non-uniform dielectric constant.

[0025] For exa...

Embodiment 2

[0028] see image 3 , which is a flowchart of a method for preparing a dielectric substrate provided in Embodiment 2 of the present invention, the method includes the following steps:

[0029] S301: Using a material with a first dielectric constant as a substrate, covering positions on the substrate except the first position, and coating a layer of adhesive on the first position.

[0030] For example, a polymer material with a first dielectric constant is used as a substrate, and a layer of epoxy resin glue is coated on the substrate. In a specific implementation process, the adhesive is not limited to epoxy resin glue, and can be replaced by other adhesives having the same function as epoxy resin glue, such as vinyl ester resin.

[0031] S302: Coating a material with a second dielectric constant on a first position of the substrate coated with the adhesive.

[0032] For example, the ceramic powder is coated on the first position where the epoxy glue is coated on the substra...

Embodiment 3

[0042] see Figure 4 , which is a flowchart of a method for preparing a dielectric substrate provided in Embodiment 3 of the present invention, the method includes the following steps:

[0043] S401: Using a material with a first dielectric constant as a substrate, uniformly mix a material with a second dielectric constant and a binder in a preset ratio to obtain a mixed material.

[0044] For example, the ceramic material with the second dielectric constant is mixed with the epoxy resin glue in a preset ratio, and the preset ratio is set so as not to affect the adhesiveness of the epoxy resin glue and is actually required.

[0045] In a specific implementation process, ceramics can be replaced by mica, glass, plastic, or metal oxides.

[0046] S402: Covering positions on the substrate other than the first position, and coating the mixed material obtained in step S401 on the first position of the substrate.

[0047] Wherein, the first dielectric constant is smaller than the ...

Abstract

Disclosed is a method for preparing a dielectric substrate, comprising the steps of: using a material having a first dielectric constant as a substrate, and coating a first position of the substrate with a material having a second dielectric constant; coating the first position and the second position of the substrate with the material having the second dielectric constant, so as to obtain a dielectric substrate with a non-uniform dielectric constant.

Description

【Technical field】 [0001] The invention relates to the technical field of composite materials, in particular to a method for preparing a dielectric substrate. 【Background technique】 [0002] Currently commonly used materials are based on the improvement and improvement of the original properties of natural materials, but with the continuous improvement of material design and preparation, the space for further improvement of various properties and functions of natural materials is getting smaller and smaller. Based on this status quo, some composite materials with extraordinary physical properties that natural materials do not possess, such as metamaterials, are produced. People can achieve various physical properties by modulating the structure and key physical scales of various levels of materials, and obtain the physical properties of materials that are ordered, disordered, or unstructured at this level or scale in nature. [0003] In the prior art, for the preparation of ...
