Patent ID: 7750764

Claim:
A method of manufacturing a coaxial-to-microstrip transition between a coaxial-line assembly and a microstrip line, the coaxial-line assembly including an outer conductor spaced apart from and extending along a common axis with an inner conductor, and the microstrip line including a dielectric substrate, a conductive strip disposed along a first primary face of the dielectric substrate, and a ground plane disposed along a second primary face of the dielectric substrate opposite the first primary face, the dielectric substrate having a leading-edge face extending between the first and second primary faces, there being an unobstructed region next to the leading-edge face that is sized longer than a cross-sectional dimension of the inner conductor, the ground plane having an interface edge that is recessed along the second primary face from the leading-edge face, the method comprising the steps of: positioning the microstrip line relative to the coaxial-line assembly, with the ground plane extending transverse to the common axis and proximate the outer conductor; and: moving the microstrip line toward the extension portion until the leading-edge face abuts the extension portion and the ground plane contacts the outer conductor.
