Abstract
Provided are coaxial transmission line microstructures formed by a sequential build process, and methods of forming such microstructures. The microstructures include a transition structure for transitioning between the coaxial transmission line and an electrical connector. The microstructures have particular applicability to devices for transmitting electromagnetic energy and other electronic signals.
Claims11
A transmission line micro structure, comprising:
- a transmission line, including:
- at least one center conductor, at least a portion of the at least one center conductor extending along a longitudinal axis;
- and
- at least one outer conductor disposed around the at least one center conductor, the at least one outer conductor including:
- first and second ends and a shortened wall portion disposed at the second end, the shortened wall portion extending parallel to the longitudinal axis a lesser extent than that of the at least one center conductor to provide an opening in the at least one outer conductor wall at a location around a selected portion of the at least one center conductor thereby exposing a longitudinal portion of the at least one center conductor;
- wherein the at least one outer conductor comprises an increased transverse dimension at the second end relative to the first end, the transverse dimension taken along a direction normal to the longitudinal axis.

A method of forming a transmission line microstructure, comprising:
- disposing a plurality of layers over a substrate, wherein the plurality of layers comprise one or more of dielectric, conductive, and sacrificial materials;
- and
- forming from the plurality of layers:
- at least one center conductor, at least a portion of the at least one center conductor extending along a longitudinal axis;
- and
- at least one outer conductor disposed around the at least one center conductor, the outer conductor including:
- first and second ends and a shortened wall portion disposed at the second end, the shortened wall portion extending parallel to the longitudinal axis a lesser extent than that of the at least one center conductor to provide an opening in the at least one outer conductor wall at a location around a selected portion of the at least one center conductor thereby exposing a longitudinal portion of the at least one center conductor;
- wherein the at least one outer conductor comprises an increased transverse dimension at the second end relative to the first end, the transverse dimension taken along a direction normal to the longitudinal axis.
