| Abstract(in English) | We evaluate mutual inductance between two parallely-placed strip lines by means of both experiments and numerical calculation. Test circuits fabricated using the SRL Nb standard process was used to measure the mutual inductances, whereas a three-dimensional inductance extraction program FastHenry was employed for calculation. Three types of strip line structures were examined: two microstrip lines without an upper ground plane (GP), two strip lines with a floating upper GP, and two strip lines with an upper GP connected to a lower GP. Each strip line structure has different dependence of mutual inductance on the line center distance, which is explained by using current and magnetic field distribution in each structure. We have found that the mutual inductance in the second line structure decreases with increasing width of the upper GP, and that the mutual inductance in the third line structure becomes its minimum when the contacts between the upper and lower GPs are placed close to the line edges. |
