Problems solved by technology

However, with the rise of the 5G operating frequency band, the periodic structure corresponding to the radome becomes very small, so the space that can be used for zigzag design becomes very limited, so the limitations of similar methods arise spontaneously

Abstract

The present invention discloses a 2.5-dimensional ultra-wide band mobile communication radome of a grid square ring loading via hole structure. The radome is a periodism frequency selective surface mainly formed by a plurality of same period unit arrays, each period unit is mainly formed by upper and lower dielectric layers, metal pasters arranged on the dielectric layers, metal via hole and an air gap layer arranged between the two dielectric layers; the electromagnetic field in the space is incident into the radome and is subjected to the selection filtering through the upper dielectric layer, the air gap layer and the lower dielectric layer in order, and the electromagnetic field with the required frequency band is outputted from the lower dielectric layer to inhibit the energy of the clutter in the condition of changing the incident angle of the electromagnetic wave. The 2.5-dimensional ultra-wide band mobile communication radome of the grid square ring loading via hole structure is suitable for the design of the ultra-wide band mobile communication radome, is wide in the passband bandwidth, very small and stable in the in-band insertion loss, especially, is stable in the wideband performance and good in the frequency selection performance when the incident electromagnetic wave is subjected to big-angle changing, and has a huge application value in the fields such as mobile communication, radar and electromagnetic shielding and the like.

Description

Technical field [0001] The invention relates to an antenna device, in particular to a 2.5-dimensional ultra-wideband mobile communication radome with a grid square ring loaded via structure, which can be used for ultra-wideband (5G) mobile communications. Background technique [0002] At present, the world's major communication preparation companies are beginning to plan ahead and actively research and develop 5G mobile communication networks. my country also launched the first and second phases of 5G mobile network research projects in 2013 and 2014, and included them in the 12th and 13th Five-Year Plans. As the beginning of a new round of competition in the global mobile communications field, 5G mobile network has become the primary task of my country's information technology development. [0003] Compared with 4G, 5G will not only further enhance the user's network experience, but will also meet the application needs of the Internet of Everything in the future. Compared with t...
