Abstract: An electronic device includes an antenna and a metal structure accommodated in a housing. In a first direction, the metal structure, at least a part of the antenna, and a part of the housing are sequentially arranged. The metal structure is provided with a non-closed slot, and in the first direction, the slot penetrates through the metal structure. The metal structure includes a first surface facing the antenna in the first direction, a vertical projection of the antenna on the first surface is an antenna projection region, and the slot extends from an edge of the first surface to the inside of the first surface and passes through the antenna projection region, so that in a working state of the antenna, an induced current that is in a same direction as a current on the antenna is formed on the first surface.

Abstract: A foldable terminal device includes a feed source, a first part, and a second part. The first part is configured with a first antenna element that is fed by the first feed source. The second part is configured with a second antenna element that is coupled to the first antenna element for coupled feeding when the foldable terminal device is folded. An operating frequency band of the second antenna element includes an operating frequency band of the first antenna element.

Abstract: This application provides an antenna having an L-shaped antenna body. The antenna body comprises a first end, a second end, and a feed point, a physical length between the feed point and the first end is greater than a physical length between the feed point and the second end, the antenna body generates resonance of a first wavelength between the feed point and the first end, and the antenna body generates resonance of a second wavelength between the first end and the second end, wherein the first wavelength is greater than the second wavelength. The antenna can have relatively good radiation performance regardless of whether the electronic device is in free space (FS) or in a handheld state.
