Problems solved by technology

[0004] At present, the commonly used protection method generally uses the protection method of PCB industrial screen printing green oil. This method is simple and mature, but the general product can only be used in a dry indoor environment. Under the action of high temperature, high humidity and sunlight, the protective layer is easy to fall off. cause the metal microstructure to be oxidized

Embodiment 1

[0031] Put the two-component epoxy resin glue with a viscosity of 5000cps in a container and stir evenly, impregnate the organic resin with the metal microstructure etched on the surface into the resin glue, and keep it vacuumed for 1 minute to remove the air bubbles on the surface, then take it out and hang it for 5 Remove the excess resin glue on the surface in 1 minute, send it to an oven for baking, and bake it at 80 degrees Celsius for 20 minutes to obtain a supermaterial with an epoxy resin film on the surface.

Embodiment 2

[0033] Put the acrylic resin glue solution with a viscosity of 1000cps in the container and stir evenly, impregnate the organic resin with metal microstructure etched on the surface into the resin glue solution, and keep vacuuming for 2 minutes to remove the air bubbles on the surface, then take it out and hang it for 3 minutes to remove the excess surface Remove the resin glue, send it to an oven for baking, and bake at 60 degrees Celsius for 120 minutes to obtain a supermaterial with an acrylic resin film on the surface.

Embodiment 3

[0035] Put the room temperature curing two-component silicone resin glue with a viscosity of 12500cps in a container and stir evenly, impregnate the organic resin with metal microstructure etched on the surface into the resin glue, and keep it under vacuum for 1 minute to remove the air bubbles on the surface, then take it out Hang for 8 minutes to remove excess resin glue on the surface, send it to an oven for baking, and cure at room temperature for 24 hours to obtain a supermaterial with a silicone resin film on the surface.

[0036] The protective film of the metamaterial in this embodiment is a thermosetting resin film, and the loss of the protective film is small, so that the metamaterial antenna prepared by the metamaterial of this embodiment will not increase the loss of the antenna due to the loss of the protective film and affect its performance. performance, and the protective film is not easy to fall off in harsh outdoor environments, which can better protect the me...

Abstract

The invention provides a metamaterial and a manufacturing method thereof. The metamaterial comprises an organic resin substrate and a plurality of metal microstructures attached to the organic resin substrate, a protective film further covers the surfaces of the metal microstructures, and the protective film is a thermosetting resin thin film. According to the metamaterial and the manufacturing method thereof, the protective film of the metamaterial is the thermosetting resin thin film, the protective film is little in loss, and thus the loss of a metamaterial antenna made of the metamaterial will not be enlarged to affect the performance of the metamaterial antenna due to the loss of the protective film. Further, the protective film cannot fall off easily in a severe outdoor environment, and thus the metamaterial antenna can be better protected.

Description

【Technical field】 [0001] The invention relates to the field of metamaterials, more specifically, to a metamaterial, a preparation method, and a prepared metamaterial antenna. 【Background technique】 [0002] Metamaterials are materials that can modulate electromagnetic waves developed in the past ten years. Metamaterials are generally composed of a certain number of metal microstructures attached to a substrate with certain mechanics and electromagnetism. These microstructures with specific patterns and materials can modulate electromagnetic waves of specific frequency bands passing through them. [0003] At present, most of the common metal microstructures of metamaterials are obtained by etching. For example, the metal microstructures etched with conductive copper foil are easily oxidized and corroded under the action of water and oxygen in the air. Protect from air and water. [0004] At present, the commonly used protection method generally uses the protection method of...
