An inverted-F antenna arrangement comprising a dielectric element structure, a radiating element on the dielectric element, the radiating element having a first end and a second end, a planar ground element, the dielectric element separating the radiating element and the planar ground element, a ground connection element on the dielectric element coupled to the first end of the radiating element for coupling the radiating element to the planar ground element, a feeder element on the dielectric element coupled to the first end of the radiating element for transferring electromagnetic radiation. The radiating element is arranged three-dimensionally on the dielectric element for forming an electrically conductive three-dimensional structure.

Antenna arrangement and method for making the same

A method of changing an antenna pattern in a radio apparatus and a radio apparatus comprising a planar antenna structure with a first and a second plane are provided. In the solution both planes are arranged to act as a radiator plane and as a ground plane and the apparatus comprises means for interchanging the usages of the planes.
