A coaxial connector comprises am outer conductor having an inner diameter D, an inner conductor coaxial with the outer conductor and having an outer diameter d, and an insulating structure having plural radii between the conductors. The diameters are selected in such a manner that the connector has a predetermined characteristic impedance (see figure I). The connector has a first cable side for connection to a coaxial cable and a second connection side for connection to a corresponding coaxial connector. The insulating structure is one piece, including a disk and tube, together having a bore with a diameter less than d. The inner conductor is inserted into the bore of the tube that is mounted in proximity to the second end. The disk periphery is fixedly mounted against the inner wall of the outer conductor. The portion of the inner conductor in the bore and the bore have a smaller diameter than d to compensate for the dielectric properties of the insulating structure in such manner that the connector has the predetermined characteristic impedance Z o where the insulating structure is located. The structure radii are selected as a function of the structure dielectric constant .epsilon. in such manner that the predetermined characteristic impedance Z o wave equation is attained.
