Abstract

The invention relates to a broadband high wave-transparent metamaterial antenna housing and an antenna system. The broadband high wave-transparent metamaterial antenna housing comprises at least one metamaterial sheet layer, wherein each metamaterial sheet layer comprises a first substrate and a plurality of artificial microstructures which are arranged on the first substrate in an array mode, and the sizes of the artificial microstructures are the same. Each artificial microstructure is of a closed structure defined by metal wires, and each closed structure is provided with a cross-shaped hollow pattern. Metal wires on the four our end portions of each cross-shaped hollow pattern extend to the two sides to form extending arms. According to the broadband high wave-transparent metamaterial antenna housing, the artificial microstructures in specific shapes are attached to the first substrates to obtain needed electromagnetic responses, wave-transparent performance of the antenna housing based on metamaterials is strengthened, and anti-interference capacity is increased. Furthermore, the antenna housing is wide in working band, high in wave-transparent efficiency, small in loss and suitable for serving as the high frequency, broadband and high wave-transparent antenna housing.

Description

technical field

[0001] The invention relates to a radome, more specifically, to a wide-band high-transparency metamaterial radome and an 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 structures with certain geome...
