Embodiment Construction

[0047] The present invention will be described in further detail below in conjunction with the embodiments and the accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0048] Such as Figure 1 to Figure 3As shown, the directional propagation radome is set on the antenna (in order to better illustrate the positional relationship between the antenna and the radome, the antenna is only shown as a feed source), the directional propagation radome includes a metamaterial panel 100, and the feed source of the antenna is connected to the The metamaterial panels 100 are arranged oppositely, and the line between the equivalent point K of the antenna feed and the center of the metamaterial panel 100 is perpendicular to the metamaterial panel 100 . The metamaterial panel 100 includes a core layer 10, the core layer 10 includes a plurality of core layer sheets 11 with the same thickness and the same refractive index distribution, the core layer she...

Abstract

The invention discloses a directional propagation antenna housing and a directional aerial system. The directional propagation antenna housing is covered on an antenna; the directional propagation antenna housing comprises a meta-material plate; the feed source of the antenna is arranged to oppose to the meta-material plate; the line between the feed source equivalent points of the antenna and the center of the meta-material plate is perpendicular to the meta-material plate; the meta-material plate comprises a core layer; the core layer comprises a plurality of core layer lamellas and the core layer lamellas have the same thickness and the same refractive index distribution; each core layer lamella comprises a sheet-like first substrate and a plurality of first artificial microstructures arranged on the first substrate; the refractive index distribution of the core layer lamellas satisfies a formula indicated in the description. The refractive index distribution of the core layer is designed in such a way that enables the electromagnetic waves emitted by the feed source of the antenna to form plane waves through the meta-material plate. The manufacture and processing are easier, the cost is lower, and a traditional antenna without orientation functions can be directionally propagated, thus orientation needs are met.

Description

technical field [0001] The present invention relates to the communication field, and more particularly, to a directional propagation radome and a directional antenna system. Background technique [0002] Metamaterials, commonly known as metamaterials, are a new type of synthetic material, which is composed of a substrate made of non-metallic materials and multiple artificial microstructures attached to the surface of the substrate or embedded in the interior of the substrate. The substrate can be virtually divided into multiple substrate units arranged in a rectangular array. Each substrate unit is attached with artificial microstructures to form a metamaterial unit. The entire metamaterial is composed of many such metamaterial units, just like Crystals are composed of countless crystal lattices arranged in a certain way. The artificial microstructures on each metamaterial unit may or may not be identical. Artificial microstructures are planar or three-dimensional structur...
