Abstract

The invention discloses a control plate, a vortex antenna and a processing method based on an artificial electromagnetic plane material, which solves the problems of high processing accuracy and high design difficulty in the generation method of microwave frequency band vortex electromagnetic waves in the prior art, and has the advantages of using artificial The electromagnetic material realizes the planarization of the phase control and has the beneficial effect of facilitating processing. The specific scheme is as follows: a control plate based on an artificial electromagnetic planar material, including multiple unit structures forming the control plate, and the multiple unit structures are designed according to the The unit structure has a metal plate and a dielectric plate on one side of the metal plate. The control plate is divided into multiple areas along its center outward. The size of the metal plate in all unit structures in each area Differs from the sheet metal dimensions of the unit structure in the adjacent area.

Description

technical field [0001] The invention relates to the communication field, in particular to a control plate, a vortex antenna and a processing method based on artificial electromagnetic plane materials. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] With the advent of the current 5G era, and people's lives becoming increasingly informationized and intelligent, the increasing number of communication services has made non-renewable spectrum resources increasingly scarce, and the amount of wireless transmission data has shown explosive growth, while the wireless communication system can The allocated frequency spectrum becomes extremely crowded, and the capacity of the mobile communication system is approaching the limit under the existing multiplexing conditions. In order to further improve the capacity and spectrum efficiency of the communi...

Problems solved by technology

[0007] High-order mode patch method: It is necessary to design a special excitation feeding method, the position of the feeding point needs to be very precise, and the purity of the OAM signal generated is not high. After the feeding position is determined, the OAM mode is fixed, and the mode cannot be changed or adjusted.

[0008] Ring array method: the ring antenna array with a fixed feed network, the main disadvantage is that the array can only generate orbital angular momentum beams of a specific mode, and cannot generate a variety of OAM modes by changing the phase of the feeder adjustment. The OAM mode is fixed to achieve vortex Swirling electromagnetic waves require a complex feeder structure, which is difficult to design and process

[0009] In general, the existing methods for generating vortex electromagnetic waves in the microwave frequency band have the problems of high processing precision and difficult design
