Abstract: A foldable electronic device includes a first housing and a second housing that are rotationally connected to each other by means of rotating shafts located on two sides, and an antenna. The first housing can switch between an unfolded state and a folded state relative to the second housing, and the antenna is disposed in a closed slot. The antenna includes a first antenna segment and a second antenna segment that are sequentially connected and disposed in a length direction of the antenna. One end of the first antenna segment is connected to a ground plate of the first housing. The first antenna segment extends from one end toward a direction in which an opening/closing region of the first housing and the second housing in the unfolded state is away from the first housing.

Abstract: Embodiments of the present invention provide a dual band adaptive concurrent processing method and apparatus. In the embodiments of the present invention, by using statistical information of services at first and a second frequency bands in the Nth adjustment period, performance of the services at the frequency bands in an adjustment period may be acquired. Based on the statistical information, and a quality of service (QoS) requirement that the services at the two frequency bands need to meet, a second coefficient of proportionality between timeslots occupied by the services at the two frequency bands in the (N+1)th adjustment period may be determined, so that switching control on first and second channels may be performed in the (N+1)th adjustment period according to the determined second coefficient of proportionality.

Abstract: One example antenna includes a radiator, and a first feed point and a second feed point that are disposed on the radiator. One end of the radiator is an open end, and the first feed point is located between the open end and the second feed point. The radiator includes a first position and a second position, where a distance between the first position and the open end along the radiator is a quarter of a target wavelength, and a distance between the second position and the first feed point along the radiator is a half of the target wavelength. The first feed point is disposed at a position that deviates from the first position by a first preset value.
