Multifrequency miniaturized terminal antenna based on loading technology unified model

The invention provides a multifrequency miniaturized terminal antenna based on a loading technology unified model, and belongs to the radio frequency antenna field. The terminal antenna comprises a ground level layer, a bottom dielectric layer, an antenna radiator and a top dielectric layer, wherein the ground level layer, the bottom dielectric layer, the antenna radiator and the top dielectric layer are arranged successively from bottom to top; the lower surface of the top dielectric layer is closely pasted on the upper surface of the bottom dielectric layer through antenna anaerobic adhesive; the lower surface of the bottom dielectric layer forms the ground level layer structure, and the upper surface of the bottom dielectric layer forms the antenna radiator; the antenna radiator includes an L type structure and an annular structure which are complementarily-loaded horizontal plane structures and are orthogonal with the same plane seamlessly; the L type structure is used for generating a high frequency band
