An antenna apparatus for an electronic device having a middle frame, a cover, and a battery located between the middle frame and the cover. The antenna apparatus includes at least one group of coupling feeding elements and at least one group of radiation elements. A first radiator and a second radiator in each group of radiation elements are arranged on an inner surface of a cover. The first radiator and the second radiator are respectively located on two sides of a coupling feeding element, and the coupling feeding element is separately coupled to feed the first radiator and the second radiator.

Antenna apparatus and electronic device

The present disclosure relates to communication tags and electronic devices. One example communication tag includes a circuit board and a chip disposed on the circuit board. Two coils are formed on the circuit board. The two coils are respectively disposed on two different conducting layers of the circuit board. Optionally, the two coils are disposed in an intersecting manner. In addition, lines for feeding the two coils are disposed close to each other.

Communication tag and electronic device

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.

Antenna and electronic device

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.
