Abstract:
A printed board, comprising:a first dielectric layer having a dielectric constant larger than that of air, the layer having an upper surface and a lower surface; a first conducting layer formed under the lower surface of the first dielectric layer; a second dielectric layer, formed under the first conducting layer, having a dielectric constant larger than that of air; a second conducting layer formed under the second dielectric layer; a first circuit element having at least first and second terminals mounted on the upper surface of the first dielectric layer; a second circuit element, mounted on the upper surface of the first dielectric layer, having at least first and second terminals to be respectively paired with the first and second terminals of the first circuit element; a first transmission line, on the upper surface of the first dielectric layer, connecting the first terminals of the first and second circuit elements; and a second transmission line connecting the second terminals of the first and second circuit elements and being routed through the first dielectric layer, the first conducting layer, and the second dielectric layer, a distance between the second terminals of the first and second circuit elements being shorter than a distance between the first terminals of the first and second circuit elements.
