Patent ID: 7460072

Claim:
A method of creating a dielectric material with a specific dielectric constant and a reduced dissipation factor, comprising: selecting two or more dielectric materials to be used instead of a single dielectric material with the specific dielectric constant, wherein at least one of the dielectric materials has a dielectric constant lower than the specific dielectric constant and at least one of the dielectric materials has a dielectric constant greater than the specific dielectric constant; calculating a height for each of the dielectric materials so that if placed one on top of another instead of using the single dielectric material the effective dielectric constant is equal to the dielectric constant of the single dielectric material; calculating the effective dissipation factor resulting from the selected dielectric materials and calculated heights; wherein at least one of the selected dielectric materials has a dissipation factor lower than the dissipation factor of the single dielectric material; and the other selected dielectric materials have a dissipation factor such that the calculated effective dissipation factor is less than the dissipation factor of the single dielectric constant.
