Abstract (en)
[origin: DE19822371A1] A reference potential connection (15) is connected via an impedance (20) to the reference potential of a reference potential plane (30). The impedance is high resistance in a first operating frequency range, and low resistance in a second operating frequency range. The impedance may be in the form of a line (20) whose length is selected according to the frequency ranges. The length may be a quarter of the operating wavelength in the second operating frequency range.- DETAILED DESCRIPTION - A radio apparatus, especially a mobile radiotelephone or a cordless telephone is also claimed
