US 10,211,506 B2 · Dual capacitively coupled coaxial cable to air microstrip transition

Abstract

A transmission line transition that couples RF energy between a coaxial cable and an air dielectric microstrip is provided. In some embodiments, the transition can combine a thin printed circuit board substrate and an insulating surface to form an effective capacitive coupling transition that can couple RF energy from the center conductor of a coaxial cable to an air microstrip. In some embodiments, the transition can include an insulating system affixed to a metallic surface, and the insulating system can secure an airstrip conductor in close proximity to an inner conductor of a coaxial cable to capacitively couple the airstrip conductor to the inner conductor of the coaxial cable. In some embodiments, the transition can employ a metallic body coated with an insulating surface to capacitively couple RF energy from the center conductor of the coaxial cable to the air microstrip.
