Signal transmission structure with an air dielectric

摘要

The dielectric constant and loss tangent of a signal transmission structure is lowered by locating discrete conductors used for signal transmission between two shields so as to form cavities between the discrete conductors and each of the shields. Each cavity is filled with any of a number and/or combination of dielectric supports and/or dielectric materials, including air. The discrete conductors are formed across the cavities so that any exposed surfaces of the discrete conductors are in contact with the dielectric material of the respective cavity.
