Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
55 words
A power divider comprising; electrically conducting coupling lines; an electrically insulating material separating said coupling lines; said coupling lines being mutually overlapping over a portion of the total length of the lines; and microwave loading means in said insulation material in the portion thereof only in the mutually overlapping region, defined by said coupling lines.
Claim 2
Dependent Claim
55 words
A power divider comprising; electrically conducting coupling lines; an electrically insulating material separating said coupling lines; said coupling lines being mutually overlapping over a portion of the total length of the lines; and microwave loading means in said insulation material in the portion thereof only in the mutually overlapping region, defined by said coupling lines.
Claim 3
Dependent Claim
46 words
A power divider, as set forth in claim 1 wherein; said coupling lines are completely overlapping over a portion of the total length thereof; wherein; said microwave loading means is placed in said insulation material only in the completely overlapping region defined by said coupling lines.
