Description

[Brief explanation of the drawing]

FIG. 1 is a diagram showing an embodiment of the coaxial line-to-microstrip line vertical converter according to the present invention, FIG. 2 is a diagram showing an equivalent circuit of FIG. 1, and FIG. 3 is a diagram showing a conventional coaxial line-to-microstrip line vertical converter. FIG. 3 is a diagram showing an embodiment of a microstrip line vertical converter. 1 is the center conductor of the coaxial line, 2 is the inner dielectric of the coaxial line, 3 is the outer conductor of the coaxial line, 4 is the signal line of the microstrip line, 5 is the dielectric substrate of the microstrip line, and 6 is the micro The ground conductor of the strip line, 7 is the connection line, 8 is the conductor surface connected to the center conductor provided on the cross section of the internal dielectric of the coaxial line, 9 is an equivalent circuit of the connection line 7, 10 is the coaxial line This is an equivalent circuit of the capacitance component existing between the conductor surface connected to the center conductor of the line and the outer conductor of the coaxial line. In addition, in the figures, the same reference numerals indicate the same or equivalent parts.
