High-frequency wireless signal generator

The invention discloses a high-frequency wireless signal generator, which comprises a first substrate, a second substrate, light-operated orientation layers, a spacer and a liquid crystal. The first substrate and the second substrate are oppositely arranged, the light-operated orientation layers are arranged on the inner surface of the first substrate and the inner surface of the second substraterespectively, the spacer is arranged between the light-operated orientation layers and form a filling space together with the first substrate and the second substrate, and the liquid crystal is contained in the filling space; the light-operated orientation layers are light-operated orientation films which are formed through multi-step overlapping ultraviolet polarization exposure and are providedwith control patterns with directors in continuous gradual change distribution in the radial direction, and the control patterns of the light-operated orientation films are used for controlling liquidcrystal molecule directors of liquid crystals to be in continuous gradual change distribution in the radial direction. The high-frequency wireless signal generator has the characteristics of wide band application, miniaturization, easy integration, high efficiency, convenience, low cost, lightness and thinness, and has great application potential in the aspects of terahertz mode multiplexing communication and the like.
