An antenna device has a first metallic layer acting as resonator plane and defining at least two radiating elements separated by a first slit, and a second metallic layer arranged substantially in parallel with the first metallic layer and acting as ground plane for the antenna device. Feeding means are connected to said first and the second metallic layer for feeding an RF signal to the antenna device, said feeding means includes a feeding point in the first metallic layer. The first metallic layer is provided with a second slit extending from said first slit with the feeding point placed on a metallized tongue between the first and the second slit, whereby surface currents have to pass around the tips of the slits towards the radiating elements.
