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.

Abstract: An antenna is provided, which includes: a main stub, a first parasitic stub, and a second parasitic stub. The first parasitic stub and the second parasitic stub are respectively arranged on two sides of the main stub. The first parasitic stub and the second parasitic stub are configured to excite resonances to improve main resonance efficiency or expand bandwidth. A frequency of the resonance excited by the first parasitic stub is greater than a frequency of a resonance excited by the main stub. A frequency of the resonance excited by the second parasitic stub is less than the frequency of the resonance excited by the main stub.
