Abstract
Abstract A microstrip probe includes a microstrip transmission line constructed from a dielectric substrate having a conductive microstrip thereon. The substrate is carried by a carrier which forms the ground plane for the microstrip transmission line. A retractable ground pin projects outwardly from the forward edge of the carrier and also extends past the forward edge of the substrate.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
125 words
A microstrip probe comprising: a generally planar dielectric substrate having a first edge, a second edge, an upper surface and a lower surface; a conductive microstrip disposed on said first surface and extending between said first edge and said second edge; a substrate carrier being substantially coextensive with said substrate and having a forward edge and at least one planar surface in a facing relationship to said second surface of said substrate, said planar surface being a ground plane, said forward edge being recessed from said first edge; and a retractable ground pin projecting outwardly from said forward edge of said substrate carrier and extending past said first edge of said substrate, said pin and said conductive microstrip being generally parallel at said first edge.
Claim 2
Dependent Claim
125 words
A microstrip probe comprising: a generally planar dielectric substrate having a first edge, a second edge, an upper surface and a lower surface; a conductive microstrip disposed on said first surface and extending between said first edge and said second edge; a substrate carrier being substantially coextensive with said substrate and having a forward edge and at least one planar surface in a facing relationship to said second surface of said substrate, said planar surface being a ground plane, said forward edge being recessed from said first edge; and a retractable ground pin projecting outwardly from said forward edge of said substrate carrier and extending past said first edge of said substrate, said pin and said conductive microstrip being generally parallel at said first edge.
Claim 3
Dependent Claim
13 words
A probe as set forth in claim 1 wherein said substrate is alumina.
Claim 4
Dependent Claim
19 words
A probe as set forth in claim 1 wherein said first edge and said second edge are opposing edges.
Claim 5
Dependent Claim
20 words
A probe as set forth in claim 3 wherein said substrate has a lateral taper narrowing toward said first edge.
Claim 6
Dependent Claim
17 words
A probe as set forth in claim 1 wherein said conductive microstrip extends over said first edge.
Claim 7
Dependent Claim
68 words
A probe as set forth in claim 1 further comprising: a probe body, said substrate carrier being mounted to said probe body; and an electrical connector carried by said probe body, said connector having a signal conductor and a ground conductor, said signal conductor engaging said microstrip conductor at said second edge when said substrate is mounted to said substrate carrier, said probe carrier engaging said ground conductor.
Claim 8
Dependent Claim
28 words
A probe as set forth in claim 6 wherein said substrate carrier has a further edge, said further edge having a protrusion in engagement with said ground conductor.
Claim 9
Dependent Claim
17 words
A probe as set forth in claim 1 wherein said substrate is releasably attached to said carrier.
