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

Wireless communication device having a reduced sar value

The invention relates to a radio communication device having at least one additional, current-conducting correction element connected to a printed board in the device. The correction element and printed board are configured in such a manner that a targeted, virtual current path elongation is brought about for an electric current induced on the printed board by electromagnetic radio fields of the antenna while the defined longitudinal and traverse dimensions of the printed board remain substantially unchanged.

Radio communication device and printed board having at least one electronically conductive correction element

An antenna for the communication terminal having a printed conductor pattern applied to a support, wherein the printed conductor pattern includes a first printed conductor pattern section, the end of which is capacitively loaded by a second printed conductor pattern section for tuning the antenna to a desired radio channel.
