AI Technical Summary
Technical Problem
In existing electronic devices, antenna components can easily cause SAR values to exceed limits during communication, resulting in excessive electromagnetic radiation.
Method used
The radiator structure of the antenna assembly was designed. Through the connection between the first, second and third radiators, the first and third radiators with longer electrical lengths jointly generate a half-wavelength mode to support the first target frequency band, disperse the resonant current and reduce the SAR value.
Benefits of technology
It effectively reduced the SAR value of the antenna assembly when supporting the first target frequency band, reduced the harm of electromagnetic radiation to the human body, and met the relevant regulatory requirements.
