Abstract
This feeder line includes: a plate-shaped dielectric substrate; a first conductor pattern dividing a first surface of the dielectric substrate into a first area and a second area; a first-area ground conductor pattern formed in the first area; a second-area ground conductor pattern formed in the second area; a second-surface ground conductor pattern formed on a second surface; a second conductor pattern connecting the first conductor pattern and one or both of the first-area ground conductor pattern and the second-area ground conductor pattern; a plurality of conductors and connecting between the second-surface ground conductor pattern, and the first-area ground conductor pattern and the second-area ground conductor pattern; and a conductive member connecting the first-area ground conductor pattern and the second-area ground conductor pattern. A length of the second conductor pattern is an odd multiple of ¼ of a wavelength of a signal propagating through the first conductor pattern.
