Abstract
An antenna device includes a first and a second internal antenna element and a common ground plane. The first element has an upper and a lower end portion. The first antenna element is adapted for use with a cellular mobile phone system and the second antenna element is adapted for use with a GPS system. To that end, the second element is elongated and adapted to receive circularly polarized radio signals by operation with linear polarization. This provides for a compact antenna device adapted for use with more than one communication system.
