Planar antenna i.e. patch antenna, for use in radio frequency identification wireless device in e.g. airship, has soft magnetic antenna element attached on partly electro-conductive carrier, and magnets extending along part of element

The antenna has a soft magnetic antenna element attached on a partly electro-conductive carrier. A hard magnetic element premagnetizes the antenna element and includes permanent magnets, which extend along a part of the antenna element. The antenna element and the permanent magnets extend adjacent to each other in a plane of the antenna. The antenna element is made of electrically insulation material. An electro-conductive structure is attached on the antenna element. The antenna element forms a closed structure. The soft magnetic antenna element is made of amorphous alloy or nanocrystalline alloy. An independent claim is also included for a method for manufacturing a planar antenna. Die Anmeldung betrifft eine planare Antenne mit einem weichmagnetischen Antennenelement, das auf einem zumindest teilweise elektrisch leitenden Träger aufgebracht ist.
