Abstract

The invention discloses a conformal antenna on the holographic artificial impedance surface. The artificial impedance surface structure comprises metal patches, a dielectric layer and a metal layer; metal patches of different sizes are corresponding to different surface impedances respectively; the surface impedances are distributed based on distribution of an interference pattern of a holographic principle; the distribution of the interference pattern of the holographic principle is corresponding to a reference wave serving as a surface wave and a target wave serving as a radiation plane wave. According to the conformal antenna on the holographic artificial impedance surface, the conformal treatment is performed on the holographic artificial impedance surface and accordingly the holographic artificial impedance surface and a complex object can be conformal, a plane holographic antenna can be conformal onto the curved surface of any complex object, and accordingly any radiation can be formed.

Description

technical field [0001] The invention relates to a holographic artificial impedance surface conformal antenna, belonging to the technical field of antennas. Background technique [0002] The basis of holographic optical technology is the phase interference of light and the diffraction of light, and the necessary condition for optical interference to occur is that two columns of light waves have the same frequency and a constant phase difference. The first step is to use the interference principle to record the light wave information of the object, and the second step is to shoot the reference beam onto the holographic film, and reproduce the object light through the diffraction of light. [0003] The mechanism of the holographic antenna is similar to optical technology. The interference pattern of the holographic antenna is formed by the interference of the radiation field of the reference antenna and the radiation field of the target antenna on the interference surface. In ...
