| Summary: | The present invention relates to small antenna structures. The invention relates particularly to internal antennas that are used in mobile stations and that are fed from one feed point.
A radio device and an antenna structure, wherein a groove () provided in a planar radiator () of the antenna is used to generate resonances for different frequency ranges, enabling the generation of more than one separate frequency ranges and at least one frequency range covering several mobile communication system bandwidths used. The groove () is implemented on the planar radiator () such that at least part of the groove is located between a feed point () and a ground point (). |
