Electromagnetic dielectric material sheet, electromagnetic dielectric particle and production method thereof

Abstract

The invention relates to an electromagnetic dielectric material, comprising a first foam material layer, a second foam material layer and a film layer, and the film layer is sandwiched and fixed between the first foam material layer and the second foam material layer; The front of the film layer is provided with a plurality of first conductor groups, and each first conductor group includes a plurality of first conductors; the central axes of the first conductors in the same first conductor group are collinearly spaced and arranged; the adjacent first conductor groups The first conductors of a conductor group are just staggered; on the back of the film layer, several second conductor groups are provided, and each second conductor group includes a plurality of second conductors; each second conductor in the same second conductor group The central axes of the conductors are collinearly spaced and arranged; the second conductors of the adjacent second conductor groups are just staggered. The electromagnetic dielectric material sheet has the advantages of high production efficiency, being able to produce electromagnetic dielectric particles with precise dielectric constants, and the like. The invention also relates to an electromagnetic dielectric particle and a method for producing the electromagnetic dielectric particle.

Description

technical field [0001] The invention relates to the technical field of electromagnetic dielectric materials, in particular to an electromagnetic dielectric material sheet, and also relates to an electromagnetic dielectric particle and a production method of the electromagnetic dielectric particle. Background technique [0002] At present, the structure of the electromagnetic dielectric particles used to make Lunberg lenses on the market is mostly a sandwich structure, and a conductive wire is sandwiched between two layers of foam material layers. The metal wire runs through its two opposite outer surfaces, so that when using electromagnetic dielectric particles of this structure to manufacture a Lunberg lens, two or more electromagnetic dielectric particles in the Lunberg lens are likely to be separated due to side contact. This leads to the conduction of the conductive metal wire, which seriously affects the dielectric constant of the Lunberg lens. In addition, such as the...

In addition, such as the Chinese patent application number CN201910391117.X, titled "A Manufacturing Method for Electromagnetic Composite Material", also discloses a technical solution for forming conductor units on a thin film, which is arranged in a rectangular array on the thin film There are several conductor units printed in the same way. In order to avoid damaging the conductor units, this production method must cut the blank space between the conductor units and the conductor units when the warp and weft cutting is made into electromagnetic dielectric particles, which is easy to produce defective products. , the production is difficult, it is easy to produce waste, and it is easy to cause waste of materials
