ABSTRACT:
A PIFA antenna device is provided which includes an HF input/output and two antenna surfaces respectively having a contact with the ground of a mobile communication terminal. The first antenna surface is configured for two independent frequencies and the second antenna surface is configured for a third independent frequency. Only the first antenna surface is connected to the HF input/output and the second antenna surface is arranged in a contactless manner with respect to the first antenna surface, whereby an electromagnetic coupling occurs between both antenna surfaces.
