Antenna and heating equipment with same

The invention relates to the technical field of communication, and discloses an antenna, comprising: a substrate comprising a first surface and a second surface opposite to each other, and a through hole penetrating the first surface and the second surface; a radiation patch which is arranged on the first surface of the substrate and is configured to radiate signals; and a grounding patch which is arranged on the second surface of the substrate and completely covers the second surface, wherein the through hole is formed in the center of the substrate, and the radiation patch and the grounding patch are electrically connected through the through hole. According to the embodiment of the invention, through the design that the grounding patch completely covers the second surface of the substrate and the radiation patch and the grounding patch are connected through the through hole in the center of the substrate, the size of the antenna is reduced, the one-way radiation efficiency of signals is improved, the anten
