The antenna element includes a first pole configured to receive a feeding signal and a second pole that is grounded. The first guiding apparatus enables a first beam generated by the antenna element to radiate in a first direction, and the second guiding apparatus enables a second beam generated by the antenna element to radiate in a second direction. A phase center of the antenna element is at an intersecting point of a first axis and a second axis, the first axis passing through a phase center of the first guiding apparatus and parallel to the first direction, and the second axis passing through a phase center of the second guiding apparatus and parallel to the second direction.

Abstract: The present invention relates to an antenna, which includes a feeding part and a radiating part. By using the feeding part and the radiating part that are perpendicular to each other and use dielectric substrates, not only a volume of a normal radiation antenna is reduced, but also a substrate integrated waveguide directly radiates energy outwards, thereby improving operating bandwidth of the antenna.

Abstract: An antenna includes a first element, a second element, and a reactance-adjustable component. The first element receives an excitation current through an electrical connection to an antenna feeder, and the second element generates an induced current through electromagnetic induction of the first element. The reactance-adjustable component is disposed at an end of the first element close to a reference plane, and/or the reactance-adjustable component is disposed at an end of the second element close to a reference plane. The reference plane uses a connection point between the first element and the antenna feeder as an origin point and is perpendicular to an axial direction of the first element. The reactance-adjustable component has an adjustable reactance value and is configured to adjust a phase difference between an excitation current and an induced current, where the phase difference has an association relationship with a target angle of radiation of the antenna.

Abstract: Embodiments of this application disclose an incoming call alert method and a terminal. The incoming call alert method includes: receiving an incoming call request; and invoking an audio/video player of a system to play audio/video corresponding to the incoming call request. The audio/video player is disposed in a system of the terminal in the embodiments of this application, so that when the terminal receives the incoming call request, the system of the terminal can play the audio/video used for incoming call alert. In this way, the terminal can alert a user by playing the audio/video without occupying additional system resources. In addition, an animation of the video and a caller ID display interface that are displayed by the terminal are integrated in terms of a visual effect, thereby improving use experience of the user.
