Claim:
An antenna arrangement of a mobile station, said arrangement comprising: a planar antenna including a ground plane and a planar radiator element which is disposed substantially parallel to the ground plane with a space therebetween, and a printed wired board which is located substantially parallel to said ground plane and said radiator element, wherein the ground plane covers a first area on the printed wired board and the radiator element covers a second area on the printed wired board, wherein: the arrangement comprises a layer of low reluctance material which layer is substantially parallel to the printed wired board and covers a third area on the printed wired board, which third area includes a number of components on a surface of the printed wire board, said layer of low reluctance material is so located that the third area on the printed wired board is at least in part outside said first and second areas on the printed wired board, and the space between the radiator element and the ground plane is substantially air, thus forming an air gap.
