[0022] See figure 1 , figure 1 Shown is the flow chart of the method for preparing the metamaterial substrate according to the first embodiment of the present invention, and the process flow of the method for preparing the metamaterial substrate includes the following steps:

[0023] Step S 101: Slowly add zinc salt into the alkaline solution under stirring to obtain a precipitate, dry the precipitate, and obtain zinc oxide powder after cooling.

[0024] Step S101 includes: stirring the alkaline solution on a magnetic stirrer, slowly adding the zinc salt above analytical purity into the alkaline solution under stirring to obtain a white precipitate, and stirring the white precipitate at a rate of 4-5°C / min The heating rate is raised to 350-1200°C for drying, heat preservation for 2-5 hours, and natural cooling to 18-25°C to obtain zinc oxide powder, wherein the molar ratio of zinc salt to alkaline solution is 1:1. In this embodiment, the zinc salt is zinc nitrate or zinc chl...

Abstract

The invention discloses a preparation method of a super material substrate, which comprises the following steps: slowly adding a zinc salt in an alkaline solution in the stirring state to obtain a precipitate, drying the precipitate, and cooling to obtain zinc oxide powder; adding the zinc oxide powder into isopropanol to form a first mixed solution, adding a coupling agent into acetone, and stirring uniformly to form a second mixed solution; slowly adding the first mixed solution into the second mixed solution, filtering, and drying to obtain modified zinc oxide; adding the modified zinc oxide into an organic solvent to carry out primary ultrasonic treatment, adding a high polymer, and stirring uniformly to obtain a third mixed solution; stirring the third mixed solution, carrying out secondary ultrasonic treatment, and drying to obtain a super material mixture; and carrying out hot pressing on the super material mixture to obtain the super material substrate. The invention also discloses a super material antenna. By artificially compounding the modified zinc oxide with the high polymer, the high-performance super material substrate can be prepared.

Description

technical field [0001] The invention relates to the field of metamaterials, in particular to a method for preparing a metamaterial substrate and a metamaterial antenna. Background technique [0002] With the rapid development of modern electronic technology, the processing and transmission of digital circuits have entered the stage of high frequency. People have higher and higher requirements for the substrate carrying the circuit. The performance of the substrate will seriously affect the circuit characteristics. Among them, dielectric properties, heat resistance Several properties such as durability, dimensional stability, moisture resistance, and strength are particularly important. The performance of the substrate depends mainly on the materials used. In the prior art, ordinary high polymers, such as epoxy resin and phenolic resin, are commonly used to make substrates, but these high polymers have poor heat resistance and poor dielectric properties, and are very unsuita...
