Abstract
A matching circuit board includes a first substrate, a second substrate, and a third substrate. The first substrate includes a first insulator, a first metal pattern, and first conductive vias. The second substrate includes a second insulator, a second metal pattern, and second conductive vias. The third substrate includes a third insulator and a third metal pattern. A capacitor is constituted by the first metal pattern, the second insulator, and the second metal pattern, and a capacitor is constituted by the first metal pattern, the first insulator, and the third metal pattern. The second metal pattern is electrically connected to the third metal pattern through the second conductive vias and the first conductive vias. The first metal pattern is separated from the first conductive vias to be positioned inside the first conductive vias, and is insulated from the first conductive vias.
