摘要:
A radio communication device is provided which includes a conductor board and a flat antenna disposed in the housing thereof and arranged at a distance from each other, thereby forming a coupling structure. A coupling area with a predetermined antenna volume is contained in the coupling structure between the antenna and the conductor board. At least one camera is arranged in, or adjacent to, the coupling area of the coupling structure such that they simultaneously form a component of the antenna volume of the coupling structure.

The present disclosure relates to an apparatus and method for transmitting power compensation in a mobile communication terminal. Under a preferred embodiment, a terminal is equipped with a power amplifier, whose output signal amplitude is dependent upon a frequency of an input signal of the power amplifier, an HF connector, an internal antenna and a connection for an external antenna and which is designed to be operated in at least one mobile radio frequency range. The configuration aims to effectively optimize a specific absorption rate value. At least one standard mobile radio frequency range is subdivided into several frequency intervals and power compensation is carried out for at least part of the frequency intervals.

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.
摘要:
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.
