摘要
An impedance compensation structure for a broadband near-field magnetic-field probe, includes: a signal via; and a plurality of grounding vias provided around the signal via to form a coaxial via array; wherein the grounding via and the signal via have an identical size, all distances of each of the plurality of the grounding vias to the signal via are equal, and the plurality of the grounding vias forms a circle centered at the signal via; wherein each of the plurality of the grounding vias is connected with a magnetic field probe top layer shield plane and a magnetic field probe bottom layer shield plane; each of the plurality of the grounding vias keeps in a conducting state from a direct current to a high frequency, in such a manner that impedance matching of the broadband near-field magnetic-field probe is achieved.
