Abstract

An embodiment of the invention discloses an antenna module, and belongs to the technical field of terminals. The antenna module comprises an antenna assembly and a polarization assembly, wherein the polarization assembly is arranged on the radiation surface of the antenna assembly and is used for carrying out polarization deflection on electromagnetic waves emitted by the antenna assembly; the polarization assembly comprises a dielectric substrate and at least one metal strip; the at least one metal strip is arranged on the dielectric substrate; the dielectric substrate is used for supportingthe at least one metal strip; and the at least one metal strip is used for carrying out polarization deflection on the electromagnetic waves, thereby the electromagnetic waves radiated by the antennaassembly are polarized and deflected by the polarization assembly, thus electromagnetic waves easily entering the direction of a human body in electromagnetic waves radiated by the antenna are blocked, so that the electromagnetic waves are well blocked, the generated current is reduced, the loss of the electromagnetic waves is reduced, the SAR value can be reduced under the condition of not reducing the radiation power, and the communication quality of the terminal is ensured.

Description

technical field [0001] The embodiments of the present application relate to the technical field of terminals, and in particular to an antenna module and a terminal. Background technique [0002] At present, terminals such as mobile phones are used as communication devices, and electromagnetic waves are generated during wireless communication. Electromagnetic waves radiate through the antenna of the terminal. When the terminal is close to the human body, the electromagnetic wave will enter the human body and induce an induced current with the electromagnetic field of the human body, which will eventually be converted into heat and consumed. In this process, the energy conversion method is mainly the conversion of electromagnetic waves into heat energy, and the size of the energy conversion is usually measured by the electromagnetic wave absorption rate (Specific Absorption Rate, SAR). Electromagnetic waves entering the human body will not only cause the energy of electromagn...
