Abstract:
1. A method for fabricating a textured dielectric substrate for an RF circuit comprising the steps of: selecting a plurality of dielectric substrate materials, each of said plurality of dielectric substrate materials having a distinct set of electrical properties different from a remainder of said dielectric substrate materials; selecting a pattern comprised of at least two types of distinct areas having said distinct sets of electrical properties and each distinct area dimensioned much smaller than a wavelength at a frequency of interest; cutting each of said plurality of dielectric substrate materials into a size and shape consistent with said distinct areas to form dielectric pieces; selectively arranging said dielectric pieces on a base plate in accordance with said pattern to form said textured dielectric substrate having at least one effective electrical property at a frequency of interest that is different from each of said distinct sets of electrical properties.
