Wide-bandwidth coaxial probe

摘要

A coaxial probe for testing of planar electric transmission line structures comprising: a probe mount comprising a coaxial connector; a center electrode mounted on the probe mount and electrically connected to a center conductor of the coaxial connector, wherein the center conductor may be placed in contact with a first point on a planar electric transmission line structure to be tested; an outer electrode mounted on the probe mount and electrically connected to ground, the outer electrode comprising a protrusion to be placed in contact with a second point on the planar electric transmission line structure to be tested; and a dielectric of non-uniform thickness between the center and the outer electrodes.
