Efficient and wideband S-G-S type strip-line interconnects

A new interconnect structures called S-G-S (signal-ground-signal) type strip-line interconnect structure is proposed. In these interconnect structures a grounded line is inserted between two adjacent signal lines of strip-line interconnects. First, these interconnects are analyzed in the frequency domain and their properties are studied analytically. Then, a matching condition is obtained to design them as a very wideband and efficient interconnects. Finally, the theoretical results are examined using an example.
