NOVELTY – The method involves utilizing metallic basic elements (3) with specific lengths, and arranging the metallic basic elements at a distance. Ends of the metallic basic elements are bent at an angle of 30-60 degrees to fold the metallic basic elements in bending zones. The metallic basic elements are divided into two semi-elements, which are provided with three segments and two patterns to form an electromagnetic device that is made of metal material such as aluminum. USE – Method for obtaining an electromagnetic device used in an electromagnetic application e.g. log periodic antenna (all claimed) in an aircraft. Uses include but are not limited to an antenna arrangement, signal filter, signal coupler, phase shifter, signal circulator, signal attenuator, radars and satellites. ADVANTAGE – The method enables reducing physical size of the electromagnetic device without causing discontinuities in magnetic field or loss in current density and changing electromagnetic performance, thus ensuring better bandwidth operation. DETAILED DESCRIPTION – INDEPENDENT CLAIMS are also included for the following: (1) an electromagnetic device (2) a log periodic antenna. DESCRIPTION OF DRAWING(S) – The drawing shows a schematic view of a zig-zag configuration of a log periodic antenna. Antenna element (1) Wave elements (2) Metallic basic elements (3) Horizontal direction (4)
