Abstract
The utility model relates to a structure capable of improving the mechanical strength of a flat-plate antenna. The flat-plate antenna comprises a basal body of a dielectric substance, a radiating metal sheet and a grounding metal sheet, wherein the grounding metal sheet is arranged on the bottom surface of the basal body of the dielectric substance; the radiating metal sheet forms ribbon shape; the two corresponding end edges of the radiating metal sheet are free ends; two corresponding side edges are extended downward to form two supporting sheet bodies in an integral forming mode; the other end of one supporting sheet body is connected with a circuit which is arranged on the basal body of the dielectric substance to be served as a signal feed-in end; the other end of the other supporting sheet body penetrates the basal body of the dielectric substance, and is connected with the grounding metal sheet to be served as a grounding end. Thus, with the two supporting sheet bodies which are in an integral forming on the radiating metal sheet, the utility model can effectively improve the mechanical strength of the flat-plate antenna, and cause the flat-plate antenna to keep parallel distance with the top surface of the basal body of the dielectric substance to prevent easy torsional deformation due to collision, ensuring the flat-plate antenna maintains due design characteristics.
