Problems solved by technology

However, with the rapid development of mobile Internet, low-frequency communication resources are almost completely utilized, which makes the electromagnetic interference between different communication systems increasingly intensified, especially frequency multiplication interference, which has seriously affected normal communication.
Existing spatial filters generally have a large profile, which is not conducive to applications in certain fields

Abstract

The invention proposes a low-section space filter. The low-section space filter comprises a filter assembly, wherein the filter assembly comprises two super structural bodies which are opposite to each other, each super structural body comprises a substrate, a plurality of first resonators and a plurality of second resonators, the substrate is provided with a first surface and a second surface which are opposite to each other, the thickness of the substrate is 0.2 millimeter, the plurality of first resonators are arranged on the first surface in an array way, each first resonator comprises a first resonant body microstructure, the plurality of second resonators are arranged on the second surface in an array way, each second resonator comprises a second resonant body microstructure, and each second resonator and each first resonator are opposite to each other and are coupled to each other. By the low-section space filter, low section can be achieved very well, and the filtering functionof a frequency-multiplication electromagnetic wave can be achieved very well.

Description

technical field [0001] The invention relates to the technical field of filters, in particular to a low-profile spatial filter. Background technique [0002] Metamaterials are a class of structural materials, whose novel physical properties are determined by the geometric properties of materials. This kind of material is relatively rare in nature or compounds, and it is usually designed artificially. Metamaterials have extraordinary physical properties that natural materials do not possess. A metamaterial is an artificial periodic structure whose unit scale is much smaller than the operating wavelength. Under long-wave conditions, it has an equivalent dielectric constant and an equivalent magnetic permeability. The electromagnetic parameters mainly depend on the resonance characteristics of its basic constituent units. Therefore, by changing the geometric shape, size, and arrangement of the basic constituent units, the distribution of electromagnetic parameters in the metama...
