Abstract: Disclosed is a mobile terminal. The mobile terminal comprises a body, an insulating bezel surrounding the periphery of the body, and a wire that is located in the insulating bezel and that acts as an antenna. The wire comprises a first line segment and at least two bending line segments that are connected to the first line segment. The bending line segments bend and extend into convex shapes from the connecting position of the first line segment, at least one bending line segment acts as the ground point of the antenna, and at least one bending line segment acts as the feed point of the antenna.

Abstract: Disclosed in the present application are a PCB and a terminal device using the PCB. At least one electric conductor is added on an exposed section of the PCB, so that the exposed section is divided into at least two sections, thereby the problem of noise interference can be solved without extensively changing the original circuit of the PCB. In this way, the project cycle and test resource can be greatly saved, and the problem of radiation noise generated by the exposed section can be completely solved.

Abstract: The invention discloses a method for reducing an SAR value of a mobile terminal, a storage medium and a mobile terminal. The method comprises: detecting and comparing signal strengths of an upper antenna and a lower antenna of the mobile terminal in real time during a call; and when it is detected that the signal strength of the upper antenna of the mobile terminal is greater than that of the lower antenna, switching the communication work of the mobile terminal to the upper antenna, and reducing the radio frequency transmitting power of the upper antenna. By adoption of the scheme, the SAR value of the mobile terminal can be reduced.

Abstract: An antenna component is provided. An orthographic projection of auxiliary antennas on a clearance area is entirely located in, partly located in, or close to a radiation-sensitive area where a specific absorption ratio (SAR) value of a frequency band needs to be reduced, so that a signal emitted from the radiation-sensitive area where the SAR value of the frequency band needs to be reduced on a primary antenna may be absorbed by the auxiliary antennas, and the auxiliary antennas generate secondary radiation.
