Abstract: The invention concerns generally the technological field of antenna arrangements in mobile stations. The invention also concerns a mobile station equipped with such an antenna arrangement. One idea of the present invention is providing a planar antenna in which the printed wired board (PWB) of the mobile station is used. The planar antenna has preferably an air gap between the radiator element (216) and the ground plate (218). In order to reduce the effects of the RF fields to other phone electronics there is a sheet of low reluctance material (245) for reducing the RF fields. The sheet of low reluctance material is so located that it covers an area of the printed wired board which is not covered by the radiator element or the ground plane of the planar antenna. The low reluctance material is preferably ferrite material, such as flexible ferrite sheet, and it may be attached to the display unit (208a, 208b) or on the PWB (234).

Abstract: The invention concerns generally the technological field of planar antenna arrangements in portable radio devices. Especially but not exclusively the invention concerns inverted-F antenna arrangements. The invention also concerns a portable radio device equipped with such a planar antenna arrangement. And additionally the invention concerns a method for producing and testing a portable radio device comprising a planar antenna. One idea of the present invention is providing an aperture (322) in the radiator element (316) of the planar antenna. An RF test point (324) is also provided for aligning the RF electronics, and the RF test point is located in such a way related to the aperture of the radiator that the test signal (320) is easily led through the aperture. It is further advantageous that an RF switch (324, 326) is provided for coupling/decoupling a connection between the planar antenna and the RF electronics. In a preferred embodiment the RF switch is integrated with the RF test point.
