Abstract (en)
An antenna part (401, 501) for portable radio devices (402, 502) comprises a planar radiator (202) bounded by a certain first outline and attachment means (211, 403, 404) for mechanically attaching the antenna part to a portable radio device. Additionally it comprises a ground plane (204, 414) which is essentially parallel to the planar radiator (202), separated from the planar radiator (202) by a certain essentially constant distance and bounded by a second outline which is essentially the same as the first outline. <IMAGE>
