Abstract
Abstract An adjustable substrate holder comprising a rectangular frame for holding at least one microstrip substrate for testing. Rails are connected to the frame along its outer edges for slidably mounting substrate clamps and electrical connector brackets. A plurality of frames may be mounted side-by-side with extended rails to hold the frames together, to accommodate an equal plurality of substrates. In such a case, the substrates are butted together and electrically interconnected by a bond across them. A continuous ground plane is formed under the substrates when two or more substrates are butted together.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
66 words
An adjustable substrate holder comprising: a. a hollow, rectangular frame for holding at least one substrate; b. rail means secured to the outer periphery of the frame; c. at least one clamp adjustably mounted on the rail means for clamping the substrate to the frame; and d. at least one connector bracket adjustably mounted on the rail means for making an electrical connection to the substrate.
Claim 2
Dependent Claim
66 words
An adjustable substrate holder comprising: a. a hollow, rectangular frame for holding at least one substrate; b. rail means secured to the outer periphery of the frame; c. at least one clamp adjustably mounted on the rail means for clamping the substrate to the frame; and d. at least one connector bracket adjustably mounted on the rail means for making an electrical connection to the substrate.
Claim 3
Dependent Claim
19 words
The adjustable substrate holder as set forth in claim 1 wherein the frame has an open top and bottom.
Claim 4
Dependent Claim
37 words
The adjustable substrate holder as set forth in claim 1 wherein the frame includes a plurality of frame members mounted side-by-side and the rail means includes at least one rail secured to all of the frame members.
Claim 5
Dependent Claim
32 words
The adjustable substrate holder as set forth in claim 3, wherein a plurality of substrates are mounted side-by-side on the frame and are electrically interconnected by a bond across their abutting edges.
Claim 6
Dependent Claim
32 words
The adjustable substrate holder as set forth in claim 4, wherein the substrates are microstrips and a continuous ground plane is formed under the substrates by the butting together of adjacent substrates.
Claim 7
Dependent Claim
57 words
The adjustable substrate holder as set forth in claim 1, wherein the clamp is laterally slidable on the rail means and includes means for setting the clamp at a particular position along the rail means for vertically adjusting the clamp with respect to the frame, whereby substrates of different dimensions may be securely held to the frame.
Claim 8
Dependent Claim
35 words
The adjustable substrate holder as set forth in claim 1, wherein the connector bracket is laterally slidable on the rail means and includes an extending contact tab for making an electrical connection to the substrate.
Claim 9
Dependent Claim
26 words
The adjustable substrate holder as set forth in claim 7, wherein the connector bracket includes means for spring biasing the connector bracket against the rail means.
Claim 10
Dependent Claim
32 words
The adjustable substrate holder as set forth in claim 8, wherein the connector bracket includes means for vertically adjusting the bracket with respect to the frame to accommodate substrates of different thicknesses.
Claim 11
Dependent Claim
36 words
The adjustable substrate holder as set forth in claim 8, wherein the substrate is a microstrip and the connector bracket includes a coaxial cable connector and means for electrically contacting the ground plane of the microstrip.
