Abstract
A portable electronic device switches between antennas in order to decrease specific absorption rate (SAR). When the portable electronic device performs wireless communication, a sensor detects a distance between an object under test and the portable electronic device. The sensor sends a message to a control circuit, and the control circuit switches to a different antenna to decrease SAR.
