Abstract: A fin-shaped multi-band antenna module, e.g., for vehicles, includes an antenna printed circuit board and a plate arranged thereupon. In a lower region the plate is mechanically connected to the antenna printed circuit board. A first monopole extends in an essentially vertical direction on the plate and is connected to the antenna printed circuit board in a lower region by a feed point. The first monopole is inductively extended in the vertical direction in an upper region of the first monopole in order to enable transmission and reception of electromagnetic waves in a lower telephone frequency range.
