ELECTRONIC DEVICE AND ANTENNA APPARATUS

WIPO Patent Application WO/2021/213182

A1

Provided in the embodiments of the present application are an electronic device and an antenna apparatus, the antenna apparatus comprising a metal body, a signal emission source, at least one antenna radiating body, and at least one feed line; a cavity is formed in the metal body, each antenna radiating body is suspended in the cavity, and the signal emission source is positioned on the outside of the metal body; the antenna radiating body comprises a first surface and a second surface facing away from the first surface, and the signal emission source feeds to the second surface of the antenna radiating body by means of the feed line; and a plurality of gaps are disposed on the surface of the metal body opposite the first surface such that the electromagnetic waves inside the main body are all emitted outside the metal body through the gaps. Compared to the prior art, the electromagnetic wave energy produced by the cavity of the metal body in the embodiments of the present application can be radiated outward to a greater extent, increasing the radiation bandwidth of the antenna apparatus, and thereby reducing the height dimension of the antenna apparatus whilst ensuring a certain radiation bandwidth.
