Abstract: This application relates to an antenna and a communication device. An example antenna includes a reflector, a resonator, a radiator, and an enclosure frame. The resonator is disposed on a side of the reflector and is configured to filter a signal of the antenna. The radiator is disposed on a side of the resonator facing away from the reflector, and the radiator and the resonator are electrically connected. The enclosure frame is disposed on the same side on the reflector as the resonator, and forms, with the reflector, an accommodating space for accommodating the resonator and the radiator. The enclosure frame has a metal surface.

Abstract: A path planning method for a virtual character, an electronic device and a non-transitory storage medium are provided. The method includes acquiring a start and end points of the virtual character in a game scene, and determining an initial path sequence connecting the start and end points based on the game scene; obtaining a fitting curve by performing curve fitting on the initial path sequence; obtaining a sampling path sequence by sampling the fitting curve; determining a plurality of sub-path sequences for forming bends in the sampling path sequence; when a turning radius of the turning path point in the sub-path sequence is less than a preset first turning radius threshold, updating a path corresponding to the sub-path sequences in the fitting curve by re-performing the curve fitting on the turning path points in the sub-path sequence, and obtaining a target path sequence by sampling an updated fitting curve.

Abstract: A dual-polarized antenna, an antenna array, and a communications device are disclosed. The dual-polarized antenna includes a base board, a horizontally polarized antenna, and a vertically polarized antenna. The substrate includes a first substrate and a plurality of second substrates stacked on the first substrate. The horizontally polarized antenna includes a first radiating element disposed on the first substrate, and a first feeding unit that feeds the first radiating element. The vertically polarized unit includes a second radiating element and a second feeding unit that feeds the second radiating element. The second radiating element includes a first metal patch disposed on each second substrate. In the foregoing technical solution, the base board formed by the stacked substrates is used as a support part, so that the horizontally polarized antenna and the vertically polarized antenna are disposed on the base board, thereby reducing space occupied by the dual-polarized antenna.

Abstract: A communications device is provided, including a metal carrier having a mounting plane with at least one mounting area, and further includes an antenna element disposed in each mounting area. The mounting area is where the mounting plane intersects a circle centered at a feedpoint of the antenna element in the area and whose radius does not exceed a specified radius. When a boundary line of the mounting area includes a boundary line, a distance from the feedpoint to the boundary line is less than or equal to a specified distance; and/or when a boundary line of the mounting area includes a vertex of the mounting plane, a distance from the feedpoint to the vertex is less than or equal to a specified distance. A feed position on the antenna element is designed to obtain relatively good antenna roundness performance and enhance an antenna signal coverage effect.

Abstract: The present invention relates to an organic light emitting device (OLED) for producing electroluminescence having, in order, for example, an anode, a hole transporting layer (HTL), a blocking layer, an electron transporting layer (ETL), and a cathode. In the devices of the present invention, the hole transporting layer comprises a polymeric material, which material may be emissive or may be doped with an emissive dopant. The blocking layer and the electron transporting layer are small-molecule materials. The presence of a blocking layer confines the emission of light to the polymer layer, which may be a HTL or a separate emitting layer (EL). The devices of the present invention are suitable for use in single color, multi-color and full-color, passive or active matrix OLED displays.
