Abstract:
To provide a multilayer substrate for transmitting/receiving a high frequency signal, the substrate having a simplified configuration and excellent high frequency characteristics. This disclosure pertains to a multilayer substrate provided with: a plurality of dielectric layers laminated together with ground layers interposed therebetween; and a signal line for inputting and outputting a signal, the signal line being formed on the surface of the dielectric layer. The plurality of ground layers include an input-side ground layer part formed in the region on the signal-input side of the signal line, an output-side ground layer part formed in the region on the signal-output side of the signal line, and an intermediate ground layer part formed in the region between the input-side ground layer part and the output-side ground layer part. The input-side ground layer part and the output-side ground layer part each have fewer layers than the intermediate ground layer part.

Claim (Index 7):
The multilayer substrate according to  claim 1 , wherein the plurality of vias have a plurality of first vias, a plurality of second vias, a plurality of third vias and a plurality of fourth vias formed in the intermediate ground layer,\n the plurality of first vias are arranged in a direction parallel to the signal line on one side of the signal line in a width direction, the plurality of second vias are arranged in a direction parallel to the signal line on the other side of the signal line in the width direction, the plurality of third vias are arranged in a direction parallel to the signal line between the plurality of first vias and the signal line, the plurality of fourth vias are arranged in a direction parallel o the signal line between the plurality of second vias and the signal line, the ground layer formed in the same layer as the signal line among the plurality of ground layers is provided as a reference ground layer, the ground layer provided on a side furthest from the reference ground layer among the plurality of ground layers is provided as a first long distance ground layer, the ground layer closest to the first long distance ground layer among the plurality of ground layers is provided as a second long distance ground layer, the first via and the second via extend in the stacking direction to electrically connect the first long distance ground layer and the second long distance ground layer, or electrically connect the reference ground layer and the first long distance ground layer, and a distance between the first via and the second via is set to be equal to or more than a half wavelength of a secondary harmonic wave of the signal transmitted and received through the signal line and less than a wavelength of the secondary harmonic wave, and the third via and the fourth via extend in the stacking direction to electrically connect the reference ground layer and the second long distance ground layer, and a distance between the third via and the fourth via is set to be equal to or more than a half wavelength of a tertiary harmonic wave of the signal transmitted and received through the signal line and less than a wavelength of the tertiary harmonic wave.
