Embodiment Construction

[0054] Such as figure 1 , Figure 11 As shown, the communication-in-motion antenna DZT of the present invention is loaded on the top position of a mobile carrier YDT (such as a vehicle, a ship, an aircraft), which includes a plurality of metamaterial flat plates 100 arranged parallel to the horizontal plane and arranged on a plurality of metamaterials. For the feed source 1 above the plate 100 , each metamaterial plate 100 corresponds to a feed point, and the feed source 1 can be switched among the multiple feed point positions under the control of the servo system. In the present invention, the feed source 1 is a traditional corrugated horn, such as the CL11R integrated tuner of Coship Electronics.

[0055] Additionally, if Figure 11 As shown, in order to protect the mobile communication antenna DZT (waterproof, sun protection, etc.), the mobile communication antenna DZT can also be covered with a radome TXZ, such as a hemispherical radome.

[0056] Such as Figure 1 to ...

Abstract

The invention discloses a mobile communications antenna. The antenna comprises a plurality of meta-material plates arranged to be parallel to a horizontal plane, and a feed source, wherein the meta-material plates are disposed in the same horizontal plane; each meta-material plate is corresponding to a feed point; the feed source may switch among the positions of the plurality of feed points under the control of a servo system; each meta-material plate comprises a core layer and a reflection layer arranged on the surface of one side of the core layer; each core layer comprises a core layer lamella or a plurality of same core layer lamellas; each core layer lamella comprises a sheet-like first substrate and a plurality of first artificial microstructures arranged on the first substrate; and the plurality of meta-material plates have the same refractive index distribution rule. The refractive index distribution of the meta-material plates is designed in an accurate manner so that plane waves at specific angles may gather at the feed source through the meat-material plates. The mobile communications antenna provided by the invention adopts the sheet-like meta-material plates to replace a traditional parabolic antenna so that the manufacture and processing are easier and the cost is lower.

Description

technical field [0001] The present invention relates to the communication field, and more specifically, relates to a mobile communication antenna. Background technique [0002] Mobile Communication is the abbreviation of "Moving Satellite Ground Station Communication System". Through the mobile communication system, vehicles, ships, aircraft and other mobile carriers can track satellites and other platforms in real time during the movement process, and continuously transmit multimedia information such as voice, data, images, etc., which can meet various military and civilian emergency communication and mobile conditions Under the needs of multimedia communication. The mobile communication system solves the problem that various vehicles, ships and other mobile carriers transmit voice, data, high-definition dynamic video images, faxes and other multimedia information in real time through geosynchronous satellites in motion. It is a major breakthrough in the current satellite...
