Abstract :
Tunability analysis based on electromagnetic modeling and simulation is performed for a miniaturized patch antenna loaded with self-biased magnetic films. The antenna includes a lossy dielectric substrate and layered thin-ferrite-film superstrate above microstrip. The structure is of multiscale and multimaterial feature and the system matrix may not be well-conditioned if the problem is described by surface integral equations (SIEs) in the integral equation approach. We use volume-surface integral equations (VSIEs) to formulate the problem and the VSIEs are solved by the method of moments (MoM) with a different implementation scheme. A numerical example is presented to illustrate the approach.
