  • Transmission line for capacitive coil
    Patent number: 9350171
    Abstract: The present invention provides a transmission line for a capacitive coil. The transmission line may include: a plurality of first cylindrical conductors; a plurality of second cylindrical conductors arranged alternately with the first cylindrical conductors in a layered structure; and dielectrics arranged between the first cylindrical conductors and the second cylindrical conductors. According to the present invention, a coaxial cable having multi-layered pairs of cylindrical conductors and dielectrics inserted between the cylindrical conductors or a cable having one or more layers of conductors separated by dielectrics is provided to thereby minimize current loss in a transmission line by compensating for line voltage drop due to self-inductance L of the line.
