| 摘要 |
The present invention provides a complementary-conducting-strip (CCS) structure for miniaturizing microwave transmission line. The CCS structure comprises a substrate; a transmission part formed on the substrate, the transmission part consisted of M metal layers and at least one connecting arm extending from the metal layers to connect to an adjacent CCS structure, the M metal layers interlaminated M-1 dielectric layer(s) perforating a plurality of first metal vias to connect the M metal layers, wherein M≧=2 and M is a nature number; and a frame part formed on the substrate, the frame part surrounding the transmission part and consisted of M-1 metal frame(s), the M-1 metal frame(s) interlaminated M-2 dielectric frame(s) perforating a plurality of second metal vias to connect the metal frames.
