Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
68 words
A HIGH-IMPEDANCE COAXIAL TRANSMISSION LINE COMPRISING, AN INNER CONDUCTOR AND A COAXAL OUTER CONDUCTOR, THE SPACE BETWEEN SAID INNER AND OUTER CONDUCTORS BEING PARTIALLY FILLED BY A TUBULAR-SHAPED TYPE Q2 FERRITE DIELECTRIC, THE RATIO OF THE QUOTIENT OF THE INNER DIAMETER OF SAID OUTER CONDUCTOR AND THE DIAMETER OF SAID INNER CONDUCTOR TO THE QUOTIENT OF THE OUTER AND INNER DIAMETERS OF SAID FERRITE DIELECTRIC BEING APPROXIMATELY 2.5.
