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 coaxial transmission line microstructure formed by a sequential build process, comprising:
- a center conductor;
- an outer conductor disposed around the center conductor;
- a non-solid volume between the center conductor and the outer conductor;
- and
- a transition structure for transitioning between the coaxial transmission line and an electrical connector
- wherein the transition structure comprises an end portion of the center conductor, wherein the end portion has an increased dimension along an axis thereof;
- and an enlarged region of the outer conductor adapted to attach to the electrical connector, wherein the end portion of the center conductor is disposed in the enlarged region of the outer conductor, the electrical connector being connected to the center conductor and the outer conductor and being attached to a rigid member.
