An antenna in motion

Abstract

The invention discloses a communication-on-the-move antenna which comprises a funnel-shaped metamaterial structure and a feed source. The metamaterial structure is composed of four same metamaterial flat boards in a splicing mode, the flat boards are in a trapezoid shape, each metamaterial flat board corresponds to a feed point, the feed source can be switched at the four feed points, each metamaterial flat board comprises a core layer and a reflecting layer arranged on the surface of one side of the core layer, and each core layer comprises one or more same core layer slices. Distribution of the refractive index of the core layer slices is accurately designed, so that electromagnetic waves emitted by the feed source are emitted in a plane wave mode after passing through the metamaterial structure, or plane waves from a satellite and with a certain angle are gathered on the feed source after passing through the metamaterial structure. According to the communication-on-the-move antenna, the four sheet-shaped metamaterial flat boards are combined to replace a traditional paraboloid antenna, manufacturing 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...
