Abstract
In an embodiment, a magneto-dielectric substrate comprises a dielectric polymer matrix; and a plurality of hexaferrite particles dispersed in the polymer matrix in an amount and of a type effective to provide a magneto-dielectric substrate having a magnetic constant of greater than or equal to 2.5 from 0 to 500 MHz, or 3 to 8 from 0 to 500 MHz; a magnetic loss of less than or equal to 0.1 from 0 to 500 MHz, or 0.001 to 0.05 over 0 to 500 MHz; and a dielectric constant of 1.5 to 8 or 2.5 to 8 from 0 to 500 MHz.
