Abstract
A flexible high-frequency signal transmission line includes a dielectric body including laminated flexible dielectric layers. A signal line is provided in the dielectric body. A grounding conductor is arranged in the dielectric body to be opposed to the signal line via one of the dielectric layers. The grounding conductor is of a ladder structure including a plurality of openings and a plurality of bridges arranged alternately along the signal line. A characteristic impedance of the signal line changes between two adjacent ones of the plurality of bridges such that the characteristic impedance of the signal line rises from a minimum value to an intermediate value and to a maximum value and falls from the maximum value to the intermediate value and to the minimum value in this order.
Claims14
A high-frequency signal transmission line comprising:
- a dielectric body including laminated dielectric layers;
- a linear signal line provided in the dielectric body;
- a first grounding conductor that is opposed to the signal line via one of the dielectric layers, the first grounding conductor having a ladder structure including a plurality of openings and a plurality of bridges alternately arranged in a longitudinal direction in which the signal line extends;
- and
- a floating conductor that is opposed to the signal line via the plurality of openings of the first grounding conductor, the floating conductor is not connected to the first grounding conductor, wherein
- the floating conductor has a rectangular shape having a longitudinal dimension extending in the longitudinal direction in which the signal line extends;
- and
- the floating conductor at least partially covers the plurality of openings.
