1. A coaxial cable, comprising:
an inner conductor; an outer conductor surrounding the inner conductor in a coaxial relationship; a first insulative material located between the inner conductor and the outer conductor at a non-bent portion of the coaxial cable and a bent portion of the coaxial cable, the first insulative material has a first dielectric constant; and a second insulative material located between the inner conductor and the outer conductor at the bent portion of the coaxial cable, the second insulative material has a second dielectric constant that is lower than the first dielectric constant. |
