Hybrid dielectric antenna capable of realizing axial directional beam and radial multi-beam radiation

The invention belongs to the technical field of antennas and provides a multifunctional hybrid dielectric antenna. The antenna comprises a hybrid dielectric plate with a hollow center, a metal flat plate, a monopole antenna and a rectangular waveguide. The hybrid dielectric plate with the hollow center is composed of a central cylindrical gap periodic cylindrical through holes and anisotropic square dielectric units for loading metal wires. The diameters of the cylindrical through holes are gradually increased from the center to the outside on the mixed dielectric plate. The metal flat plate is loaded on the lower surface of the hybrid dielectric plate. The monopole antenna is fixed in the center of the hybrid dielectric plate. The rectangular waveguide is fixed in the axial focus positionof the integral hybrid dielectric plate through a bracket. According to the invention, axial high-gain directional radiation and radial multi-beam radiation functions can be achieved at the same time, and the antenna can be
