ANTENNA APPARATUS AND ELECTRONIC DEVICE

The present application relates to the technical field of antennas. Disclosed are an antenna apparatus and an electronic device. The antenna apparatus comprises at least one dielectric substrate, a ground metal layer, a radiation patch, a first feed structure, a first deflection patch, and a radio frequency chip. The ground metal layer, the at least one dielectric substrate, and the radiation patch are stacked; the first feed structure penetrates through the at least one dielectric substrate; a first end of the first feed structure is connected to the radiation patch; a second end of the first feed structure passes through the ground metal layer and is electrically connected to the radio frequency chip; a first excitation signal fed by the radio frequency chip is used for exciting the radiation patch to radiate a beam; the first deflection patch is fixed on a first side of the radiation patch. According to the present application, when the radiation patch radiates the beam, a beam radiation direction is deflected by means of different forms (crystalline and amorphous) of the first deflection patch, so that the beam radiation direction is adjusted, and the spatial coverage of the antenna apparatus is improved.
