Abstract: An antenna device is described. The antenna device 100 comprises at least two antenna elements each of comprising a first radiating element 110 and a corresponding second radiating element 120. The second radiating element 120 extends in a height direction along a common center axis A from a foot of the antenna device 100 to its corresponding first radiating element 110. The first radiating element 110 extends in a length direction outwards from the common center axis A. The length of the first radiating element 110 defines the maximum supported wavelength. Furthermore, each first radiating element 110 has a greater length than its width and each first radiating element 110 is electrically coupled to its corresponding second radiating element 120 along the length direction, so that the second radiating element 120 can contribute to the smaller wavelengths.
