ABSTRACT:
The present disclosure relates to a substantially flat antenna structure which includes a frame earth terminal and at least one HF feed connection, which can be used for at least two frequency bands. From one foot area outwards, which includes the frame earth terminal, the antenna structure includes two antenna branches. Two distanced HF feed connections are provided in the foot area. The two antenna branches of the antenna structure are embodied in such a way that the associated frequency bands overlap.
