Extraction of electrical properties of nanomagnetic materials through meander-shaped inductor and inverted-F antenna structures

This paper presents processing, integration and characterization of a new class of magneto-dielectrics consisting of metal nanoparticles in a polymer matrix for antenna applications. These nanomagnetic materials exhibit several attractive features for antenna applications, such as simpler thick-film processing, higher permittivity and permeability, and lower loss. Extraction of permeability and loss for such materials is usually cumbersome because both the permittivity and permeability are unknown. The meander-shaped inductor structures developed and reported here allow simpler fabrication and characterization of permeability and magnetic loss. Inverted-F antenna structures were designed, fabricated and tested to verify this method.
