1. A ceramic patch antenna structure, comprising:
a composite material base body, composed of a first dielectric constant material and a second dielectric constant material, having a front surface, a rear surface and a through hole, wherein a dielectric constant of the first dielectric constant material is higher than a dielectric constant of the second dielectric constant material;
a radiation metallic layer, provided on the front surface of the composite material base body, having a perforation corresponding to the through hole;
a grounding metallic layer, provided on the rear surface of the composite material base body, having an opening corresponding to the through hole, and the opening having an internal diameter greater than an internal diameter of the through hole; and
a signal feeding element, provided in the through hole, the signal feeding element having a shaft with a projection formed thereon, two distal ends of the shaft extending to form a head and an end portion, respectively;
wherein the signal feeding element is screwed to the through hole, the projection on the shaft destroys an internal wall of the through hole to latch in the through hole, the head is electrically connected with the radiation metallic layer, and the end portion passes through the through hole and the opening without contacting with the grounding metallic layer;
wherein a diameter of the shaft is larger than a diameter of the end portion; and
wherein a latching portion is formed on a surface of the internal wall of the through hole, and the latching portion is a thread surface or a groove.
