Embodiment Construction

[0045] Such as figure 1 , Figure 11 and Figure 12As 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), and it includes a funnel-shaped metamaterial structure JG, and the metamaterial structure JG consists of four The same trapezoidal metamaterial slab 100 is assembled to form, and each metamaterial slab 100 corresponds to a feed source 1 . The depth of the metamaterial structure JG (that is, the distance from the upper opening SK to the lower opening XK of the metamaterial structure JG) can be adjusted, and the depth of the metamaterial structure JG at the initial position is related to the position of the geosynchronous satellite and the mobile carrier to be communicated (Its depth has actually determined the elevation angle of each metamaterial flat panel 100), preferably the depth of the metamaterial structure JG at the initial position is set in such a w...

Abstract

The invention discloses a communication-on-the-move antenna which comprises a funnel-shaped metamaterial structure. 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 source and comprises a core layer and a reflecting layer arranged on the surface of one side of each core layer, each core layer comprises a core layer slice or a plurality of same core layer slices, and each core layer slice comprises a first sheet-shaped substrate and a plurality of first artificial micro-structures arranged on the first substrate. Distribution of the refractive index of the core layer slices is accurately designed, so that electromagnetic waves emitted by each feed source are emitted in a plane wave mode after passing through the corresponding metamaterial flat boards, or plane waves from a satellite and with a certain angle are gathered on the corresponding feed sources after passing through the metamaterial flat boards. 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...
