摘要： Embodiments of this application disclose a terminal antenna and a wearable device, and relates to the field of antenna technologies. Impact of a human body on radiation of the antenna can be reduced, and radiation performance of the antenna can be improved. A specific solution is as follows: The terminal antenna includes a first radiator, a reference ground, and a metal ring structure. The first radiator has a hollow structure. A projection of the reference ground on a plane on which the first radiator is located is located inside the hollow structure of the first radiator. A projection of the metal ring structure on the first radiator is not beyond the structure of the first radiator. When the wearable device is in a worn state, a distance between the metal ring structure and a user is less than that between the first radiator and the user. Therefore, the radiation performance of the antenna of the wearable device is improved.

摘要： This application provides a terminal antenna and a mobile terminal device. The terminal antenna includes a frame, a first feed, and a second feed. A first gap and a second gap that partition the frame are provided on the frame, to form a first conductor, a second conductor, and a third conductor. A part of the frame on a side of the first gap away from the second gap forms the first conductor, a part of the frame on a side of the second gap away from the first gap forms the second conductor, and the frame between the first gap and the second gap forms the third conductor. The first feed is electrically connected to the first conductor, so that the first conductor radiates a signal, and the second feed is electrically connected to the second conductor, so that the second conductor radiates a signal in a low band. The terminal antenna further includes a control circuit. One end of the control circuit is grounded, and the other end is electrically connected to the first conductor, to control the first conductor to radiate a signal in a medium-high band or radiate a signal in the low band. The terminal antenna can operate in 4G and 5G low bands, and has good mobile communication performance.

摘要： The present invention discloses an antenna switching method and a terminal antenna and relates to the field of antenna technologies, so that, in different attitudes, the antenna provides corresponding polarization characteristics to perform signal transmission and reception in the corresponding attitudes. A specific solution involves: receiving, by the electronic device, a target signal with a target polarization characteristic, controlling the terminal antenna to operate in a first state when an attitude of the electronic device is the first attitude, where the terminal antenna in the first state has a first polarization characteristic, and the first polarization characteristic corresponds to a target polarization characteristic of a target signal received in the first attitude; and controlling the terminal antenna to operate in a second state when the attitude of the electronic device is the second attitude, where the terminal antenna in the second state has a second polarization characteristic, and the second polarization characteristic corresponds to a target polarization characteristic of a target signal received in the second attitude.
