Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
108 words
A two wire radio frequency energy transmission line comprising a first tubular extendible element formed of a rolled elongated web of material which curls when unrolled into a generally tubular shape, and a second rolled extendible means formed on at least one surface of said first element and having a pair of laterally spaced elongated means capable of propagating radio frequency energy independent of said first element when unrolled forming said two wire transmission line, and means for coupling radio frequency energy to said pair of elongated means in the area at or after where said pair of elongated means goes from a rolled to an extended condition.
Claim 2
Dependent Claim
108 words
A two wire radio frequency energy transmission line comprising a first tubular extendible element formed of a rolled elongated web of material which curls when unrolled into a generally tubular shape, and a second rolled extendible means formed on at least one surface of said first element and having a pair of laterally spaced elongated means capable of propagating radio frequency energy independent of said first element when unrolled forming said two wire transmission line, and means for coupling radio frequency energy to said pair of elongated means in the area at or after where said pair of elongated means goes from a rolled to an extended condition.
