ABSTRACT:
A Portable communication device includes in an interior of the portable communication device a ground plane and an antenna arrangement. The antenna arrangement includes 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. The antenna arrangement further includes 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 plane and in an open position separates the second radiating antenna element from the ground plane.
