This application discloses a method for fabricating a microcoaxial transmission structure and the microcoaxial transmission structure itself. By directly forming grooves and metal conductors on a substrate and then bonding them together, the microcoaxial transmission structure is effectively formed, avoiding complex steps such as ultra-thick photolithography, repeated electroplating and polishing, and long-term sacrificial layer release.
