要約(英語): A dual composite right/left handed (D-CRLH) differential transmission line common mode filter had been proposed and reported as a new type common mode filter previously by our group. A D-CRLH differential transmission line has common mode filter function because its equivalent circuits in differential signal mode and common noise mode were different. However, our first prototype device had large insertion loss of about 8 dB. Therefore transmission characteristics of the device have been improved by improvement of device structure and optimization of its design dimension. In this paper, we descripted fundamental of D-CRLH differential transmission line as common mode filter function and reported transmission characteristics of an improved device we fabricated. As an experimental result, transmission coefficient of the fabricated device was about -2 dB in differential mode and -20 dB below in common mode at the frequency range from 3.8 GHz to 4.0 GHz. Finally, we described our vision of a D-CRLH differential transmission line common mode filter.
