Title: Method for controlling angle of antenna according to sar level and method for indicating sar level to user in mobile phone
Inventor: KANG WANG YU
IPC: H04W88/02
Filed: 2003-09-25
Abstract: A method for controlling an angle of an antenna according to an SAR(Specific Absorption Rate) value in a mobile communication terminal and a method for displaying the SAR value to a user are provided to store an SAR value in accordance with a transmit power, and to control an angle of an antenna according to the stored SAR value, thereby reducing an influence of an electromagnetic wave by forming an interval between the antenna and a human body. When a call signal is received in a standby state of a mobile communication terminal or a user originates a call, the terminal is in speech state or in the standby state(S210,S220). If the terminal is in the speech state, a controller reads an SAR value in accordance with a transmit power from a memory(S230). The controller controls an angle of an antenna according to the read SAR value(S240). If the SAR value is changed in the speech state, the controller controls the angle of the antenna according to the changed SAR value, and if the call is terminated, the antenna is returned to an original position(S250,S260).
