1. Antenna arrangement to be provided in the interior of a portable communication device, comprising:
an antenna element combination including
a first radiating antenna element to be connected to a feeding potential and dimensioned for resonating in a first frequency band, and
a second radiating antenna element dimensioned for resonating in a second frequency band;
at least one first element joining switch that in a closed position interconnects elements of the antenna element combination for dimensioning the antenna element combination for resonating in a third frequency band and in an open position separates these elements from each other; and
a grounding switch which in a closed position joins the second radiating antenna element to a ground potential and in an open position separates the second radiating antenna element from the ground potential.
