| Outline of Final Research Achievements |
In this research, a new structure which realizes the relative permeability becomes 1 or less in the broadband in the microwave range is developed. First, we developed a simulation method. The developed method is based on the equivalent circuit and the method can be analyzed at a higher speed than the electromagnetic field analysis method that is generally used, which enables simulation at high speed. We developed a new structure with a relative magnetic permeability is less than 1 in a broadband frequency range. It was confirmed that this structure has relative magnetic permeability is less than 1 in a broadband frequency range. the bandwidth of the structure is almost doubled band compared to the conventional structure. This structure can be applied to miniaturization of antennas.
