Problems solved by technology

Due to the advantages of high resistivity, low dielectric constant and easy processing, polymers are often used as packaging materials or substrate materials, but they have poor thermal properties and are not suitable for high-heat, high-integration and high-power circuits.
[0004] Traditional substrate resins mostly use phenolic resin and epoxy resin. At present, glass fiber-r

Abstract

The invention provides a metamaterial base plate. Materials for preparing the metamaterial base plate include polystyrene and alumina fiber, wherein the alumina fiber accounts for 2 to 48 wt% of polystyrene. The invention also relates to a preparation method of the metamaterial base plate, and a metamaterial antenna prepared with the metamaterial base plate. The alumina fiber and polystyrene have low cost, and are simple in preparation technology, so the cost performance of the metamaterial base plate is high; the metamaterial base plate prepared with the alumina fiber serving as the filler of polystyrene has high heat resistance, low consumption and high strength; meanwhile, the metamaterial base plate is prepared with simple process and low cost; due to the high heat resistance, the metamaterial base plate can be applied to circuits with high temperature, high integrity level and high power; and the metamaterial base plate has low consumption and high strength, therefore, the requirement of the metamaterial antenna to the performance of the base plate can be met.

Description

【Technical field】 [0001] The invention relates to the field of metamaterials, in particular to a metamaterial substrate, 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] Electronic products are developing in the direction of thinning, high performance and multifunctionality. For this reason, substrate materials should not only have low dielectric constant and dielectric loss, but also have excellent thermal, electrical and mechanical properties. Due to the advantages of high resistivity, low dielectric constant and easy processing, pol...
