Abstract

The invention discloses a metamaterial composite broadband wide-angel scanning matching layer. The metamaterial composite broadband wide-angle scanning matching layer includes a metamaterial broadband wide-angle matching layer (1) and a split type medium broadband wide-angle matching layer (2), wherein one side of the split type medium broadband wide-angle matching layer (2) is adhered to one side of the metamaterial broadband wide-angle matching layer (1), and the two layers are adhered through a prepreg. The metamaterial composite broadband wide-angle scanning matching layer provided by the invention is designed based on the metamaterial broadband wide-angle matching layer, and introduces more flexible and multi-dimensional electromagnetic parameter regulation and control; a matching state of an antenna, particularly an active reflection coefficient during large-angle scanning, is improved in a broadband, and antenna working bandwidth is further expanded; and antenna unit beamwidth is expanded, an achievable gain of an array antenna can also be improved, and a gain drop during array large-angle scanning can be reduced.

Description

technical field [0001] The invention relates to the technical field of power conversion, in particular to a metamaterial composite wide bandwidth angular scanning matching layer, a metamaterial wide bandwidth angular matching layer and a method for manufacturing the metamaterial composite wide bandwidth angular scanning matching layer. Background technique [0002] The reflection coefficient of the aperture surface of the phased array antenna changes with the scanning angle, scanning surface and radiation polarization. When the antenna scans at a large angle, the mismatch between the antenna and the free space is serious, which affects the working bandwidth and scanning angle of the antenna. Adjusting the matching method of the unit feeder cannot compensate for this change in the reflection coefficient. They can only compensate for a specific scanning angle, scanning plane, and polarization, and there are still mismatch problems in other states. The effect of wide bandwidth...
