Abstract:
1. Measuring probe for measuring high frequencies, comprising a contact end for contacting planar structures and a co-axial cable end for connection to a co-axial cable; a co-planar conductor structure having at least two conductors arranged between the contact end and the co-axial cable end; and a solid dielectric mounting the co-planar conductor structure, the dielectric being arranged on (a) the co-planar conductor structure, and (b) at least one side of the co-planar conductor structure in a central section of the probe so the dielectric is between and spaced from the co-axial cable end and the contact end, each conductor in the co-planar conductor structure including a portion formed to be individually free in space and resilient in relation to the dielectric, a respective gap being formed between each pair of conductors in the co-planar conductor structure from the co-axial cable end to the contact end in such a way that a constant characteristic impedance is obtained from the co-axial cable end to the contact end, the ground plane conductor and the signal conductor being mounted in the same plane of the solid dielectric.
