Abstract
A coaxial wiring structure that is constructed by depositing and etching a series of conductor layers and insulator layers. More specifically, the shielded transmission line of the invention comprises a first plate structure disposed on a first insulator layer disposed on a substrate; a second insulator layer disposed on the first insulator layer and the first plate structure, the second insulator layer having first troughs exposing end portions of the first plate structure; a central conductor and at least two peripheral conductors disposed on the second insulator layer, the two peripheral conductors contacting the end portions of the first plate structure through the first troughs; a third insulator layer disposed on the second insulator layer, the two peripheral conductors, and the central conductor, the third insulator layer having second troughs exposing respective ones of the peripheral conductors; and an upper plate structure formed on the third insulator layer, the upper plate structure contacting the peripheral conductors through the second troughs. In combination, the upper plate structure, the peripheral conductor structures and the lower plate structure surround the central conductor and are insulated therefrom by the respective insulator layers. The surrounding conductors are coupled to ground potential, and high frequency transmission signals are propagated along the central conductor.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
