Problems solved by technology

These methods may require changes to the structure of the antenna itself, which is not easy to implement, or require sacrificing certain parameters, and the gain outweighs the gain
At present, there is a lack of a solution in the existing technology that can improve the directivity coefficient and reduce the side lobe without changing the structure of the antenna itself or sacrificing some parameters.

Abstract

The invention provides a conductive geometric structure and a meta-material. The conductive geometric structure has resonance responsiveness, a positive effective dielectric constant and negative equivalent permeability, and is used for changing a wave transmitting rate and phase shift along with the change of the angles of incident waves of an H-shaped surface. The conductive geometric structure and the meta-material provided by the invention have the capability of changing the wave transmitting rate and the phase shift along with the change of the angles of incident waves, and under the condition that the structure of an antenna itself is not changed, accordingly improve the directivity factor of the antenna and reduce the sidelobe of the antenna at the same time.

Description

technical field [0001] The invention relates to the communication field, in particular, to a conductive geometric structure and a metamaterial. Background technique [0002] In the current antenna technology, improving the directivity coefficient and reducing the side lobe are two important research topics. The directivity coefficient is a parameter used to indicate the degree to which the antenna radiates electromagnetic waves in a certain direction (that is, the sharpness of the directivity pattern). In the medium wave and short wave bands, the directivity coefficient is about several to tens; in the meter wave range In the centimeter wave band, it can be as high as several thousand, or even tens of thousands. The higher the directivity coefficient, the better the performance of the antenna. The side lobe can represent whether the line power radiation is concentrated. The side lobe is relative to the main lobe. The smaller the width of the main lobe, the sharper the patte...
