Document Type and Number:
Japanese Patent JP7152716
Kind Code:
B2
Abstract:
To achieve both of the proper flexibility and excellent transmission characteristic in a flexible waveguide of transmitting an electric wave at the frequency equal to or greater than the desired millimeter wave (including the sub-millimeter wave).SOLUTION: A flexible waveguide 50 includes: a linear dielectric body 51 which has the uniform dielectric constant in the longitudinal direction and in which the cross sections perpendicular to the longitudinal direction have the same shape; and a flexible external conductor 53 which is arranged on the outer periphery of the linear dielectric body 51 and has a metal layer on the inner surface. The cross section of the dielectric body 51 forms the ridge shape. The external conductor 53 has the braid structure.SELECTED DRAWING: Figure 8
