Abstract
A wireless terminal with a reduced Specific Absorption Rate (SAR) peak value and a method for reducing an SAR peak value by using the wireless terminal are disclosed. The wireless terminal with a reduced SAR peak value includes a first antenna configured to receive or transmit a communication signal, and further includes: a second antenna configured to feed a coupling signal when the first antenna receives or transmits the communication signal, and a signal processing module configured to process the coupling signal to reduce an SAR peak value of the communication signal for a human body. The energy of a superposed signal in a human body orientation is reduced by superposing the coupling signal with the communication signal, so as to reduce the SAR peak value effectively.
