Abstract
To control antenna characteristics in an electronic device, a method for operating the electronic device may include identifying communication states related to a first radio access technology (RAT) and a second RAT, determining a mode of a tuner which controls characteristics of an antenna for the second RAT, based on the communication states, and controlling the tuner according to the mode.
Claims18
A method for operating an electronic device, comprising:
- performing a first communication of a first radio access technology (RAT) through a first antenna of the electronic device, the first RAT including wireless local area network, Bluetooth, or global positioning system (GPS),
- identifying whether performing of a second communication of a second RAT through a second antenna of the electronic device interferes with the first communication through the first antenna, the second RAT including a cellular communication,
- if performing of the second communication interferes with the first communication, identifying a first communication state related to the first RAT and a second communication state related to the second RAT;
- determining a mode of a tuner configured to control impedances of the second antenna for the second RAT, based on both the first communication state and the second communication state;
- and
- controlling the tuner according to the mode,
- wherein the mode of the tuner includes:
- a first mode in which the impedance of the second antenna is optimized for performing the first communication through the first antenna, and
- a second mode in which the impedance of the second antenna is optimized for performing the second communication.
