Abstract:
In order to reduce the SAR value in a wireless communication device (MP), an additional, current-conducting corrective element (CE1) is coupled to and configured in relation to the printed circuit board (LP) and the antenna (AT1) such that the amplitude level (IM1, NIM1) and/or the phase angle of electrical currents (I3, I1, I2) on the antenna (AT1), the printed circuit board (LP), and the corrective element (CE1) are adjusted relative to each other in such a way that the SAR distribution resulting from such currents becomes minimal.
