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: 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.
