Abstract: This application provides an electronic device, relates to the field of electronic device technologies, and can improve radiation efficiency of an antenna in the electronic device. The electronic device includes a reference ground layer, a first radiator, and a second radiator, where the reference ground layer has a first edge, and a second edge and a third edge that are respectively connected to two ends of the first edge. The first radiator has a first ground point and a first feed point that are disposed at an interval, and the first ground point is electrically connected to the reference ground layer. The second radiator is electrically connected to the first edge of the reference ground layer, or an end section that is of the second edge and that is connected to the first edge, or an end section that is of the third edge and that is connected to the first edge. An electrical length of the reference ground layer in a first direction is a ½ wavelength of a main resonant band of the first radiator, and a parasitic resonant band generated by the second radiator when a radio frequency signal is fed at the first feed point is lower than the main resonant band generated by the first radiator when the radio frequency signal is fed at the first feed point. The electronic device provided in this application is used for a communication system.

Abstract: A ranging system and a mobile platform are provided. The ranging system includes a laser, a coaxial optical lens group, a mirror group, a moving component, and a processing circuit. When the laser emits laser light to the mirror group by using the coaxial optical lens group, the moving component drives the mirror group to rotate, so that the laser light is irradiated to a measured object at different angles, to implement ranging of the measured object. The moving component bears a light object, so that the moving component rotates quickly. Therefore, if the ranging system is installed on a vehicle, the ranging system can implement fast ranging of incoming and outgoing vehicles and meet a ranging requirement of an autonomous driving technology.
