Abstract

An antenna device for a radio communication device, comprises a ground plane (1), connected to a conductive second plate (2) by means of a conductive grounding means (9). Between the ground plane (1) and the second plate (2) a conductive third plate (3) is arranged. The third plate (3) is provided with a feed portion (35), which is to be connected to circuitry of the radio communication device, whereby it is achieved that received/transmitted signals in a first frequency band, are capacitively coupled between the second (2) and third (3) plates.
