High Q inductor design using modified magnetic substrate structure

The antenna was set in a three-dimensional substrate to increase antenna's quality factor. The best substrate shape shows significant improvement in measurement and simulation up to 18.35 % and 22.472 %. In this article we designed four different substrate shapes to analyze each inductor, resistance and quality factor. The errors of measurement and simulation results were under 5%. The efficiency was raised by using the most appropriate substrate models.
