Abstract:
A mobile radio transmitting and receiving device, comprising:an electrically effective antenna body; a dielectric body mounted in a near field of the electrically effective antenna body such that the dielectric body can move, and whereupon an extent to which the dielectric body and the electrically effective antenna body overlap in the near field is changed; an adjusting part for adjusting a position of the dielectric body; a detection part for detecting at least one physical variable which represents a function of transmission and reception quality of the radio transmitting and receiving device; and a control device connected to the detection part for controlling the adjusting part, via at least one control signal as a function of the at least one physical variable, until the extent of the overlap ensures an optimum value for the at least one physical variable which represents a function of the transmission and reception quality of the radio transmitting and receiving device.
