Claim Text:
1. A wireless terminal with a reduced Specific Absorption Rate (SAR) peak value, which comprises a first antenna configured to receive or transmit a communication signal, wherein the wireless terminal further comprises: 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; and a human body sensor, configured to sense and output orientation information of the human body; wherein the signal processing module is further configured to: receive the orientation information of the human body, determine, according to the orientation information of the human body and an amplitude and a phase of the communication signal, the amplitude and the phase of the coupling signal corresponding to a minimum value of the energy of the near-field superposed signal in the human body orientation, and adjust the coupling signal according to the determined amplitude and phase of the coupling signal.
