Mobile terminal, and method for improving radiation performance and specific absorption rate of an antenna of a mobile terminal

摘要

A method and a mobile terminal of improving radiation performance and Specific Absorption Rate (SAR) of an antenna are provided. The mobile terminal includes a controller for generating a control signal for switching a ground according to a frequency band used by an antenna, and a switch unit for switching a contact point for each frequency band according to the control signal.

主权项

1. A mobile terminal comprising:
a controller configured to determine a frequency band, to generate a control signal according to a switching table including a switching condition corresponding to the determined frequency band, and to control connection between a ground and a ground auxiliary part based on the control signal, wherein the switching table is generated by:
collecting, according to the frequency band, at least a subset of switching conditions for which a Specific Absorption Ratio (SAR) is within a predetermined SAR range,selecting, according to the frequency band, a switching condition from the collected at least a subset of switching conditions for which a minimum Voltage Standing Wave Ratio (VSWR) appears, andgenerating the switching table based on the selected switching condition.
