However, the convex lens still needs to manufacture a curved surface with uneven thickness to achieve the desired effect, and the thickness of the convex lens is relatively thick, which is not conducive to the trend of miniaturization of existing equipment

Embodiment Construction

[0032] Light, as a kind of electromagnetic wave, when it passes through glass, because the wavelength of light is much larger than the size of atoms, we can use the overall parameters of the glass, such as the refractive index, rather than the detailed parameters of the atoms that make up the glass to describe The response of glass to light. Correspondingly, when studying the response of materials to other electromagnetic waves, the response of any structure in the material whose scale is much smaller than the wavelength of the electromagnetic wave to electromagnetic waves can also be described by the overall parameters of the material, such as the dielectric constant ε and magnetic permeability μ. By designing the structure of each point of the material, the dielectric constant and magnetic permeability of each point of the material are the same or different, so that the overall dielectric constant and magnetic permeability of the material are arranged in a certain order, and ...

Abstract

The invention discloses a horn antenna which comprises an antenna body and a metamaterial attached onto the caliber surface of the antenna body or located right in the front of the caliber surface of the antenna body, and the central axis of the antenna body penetrates through the central point of the metamaterial. The metamaterial comprises a base material and a plurality of artificial metal microstructures periodically distributed on the base materials, refractive indexes at all positions of the metamaterial are circularly distributed, the refractive index at the circle center is the largest, the refractive indexes are smaller gradually along with increasing of the radius, and the refractive indexes at the same radius position are identical. The metamaterial with the converging function is additionally arranged on the existing antenna body, electromagnetic waves radiated by the antenna body are converged by the metamaterial and then are re-radiated, the radiation angle of the re-radiated electromagnetic waves is larger than the radiation angle of the electromagnetic waves before converging, and the radiation range of the antenna body is broadened.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a horn antenna. Background technique [0002] Horn antenna refers to the antenna whose waveguide terminal is opened into a horn shape, and its name comes from its shape. The horn antenna has a simple structure and is easy to control the pattern, which can be used as a directional antenna or as a feed source. [0003] The radiation angle of the horn antenna is determined by the size of the horn mouth. When the radiation angle needs to be enlarged, the size of the horn mouth needs to be enlarged accordingly. In the prior art, the method of expanding the radiation angle without increasing the size of the horn mouth is generally to add a concave lens at the front end of the horn antenna. Due to the divergence effect of the concave lens, the radiated electromagnetic waves are diverged to expand the radiation angle. Due to the difficulty in manufacturing the curved surface of the co...
