Embodiment Construction
[0030] Such as Figure 1-Figure 5 As shown, the present invention is a fractal dielectric resonant antenna used as a parabolic feed source with a smaller focal diameter ratio F / D, and its structure includes: a feeding circular waveguide 1, a cylindrical dielectric matching section 2 in the tube, and a conical tube outside the tube The dielectric radiator 3 and the hyperbolic reflective surface 4 at the bottom of the cone. The hyperbolic reflective surface 4 at the bottom of the cone is located on the bottom surface of the conical dielectric radiator 3 outside the tube.
[0031]The front section of the dielectric radiator is a cylinder with a diameter of d and a height of h, and the back section is a cone with a bottom diameter of D and a height of H; the front section is processed into several small sections with different diameters by cutting technology, each The small section of dielectric block is drilled or grooved respectively, and then the entire front section is inserte...
