  • Publication number: 20220247059
    Abstract: An impedance converter includes a dielectric substrate, a ground layer formed on a rear surface of the dielectric substrate, and a signal line formed in a layer from an inside to a front surface of the dielectric substrate with a distance to the ground layer gradually changed along a signal transfer direction. The signal line includes a plurality of lines stacked in the layer from the inside to the front surface of the dielectric substrate with the distance to the ground layer gradually changed along the signal transfer direction.
