Ceramic dielectric materials for microwave resonator arrays

Integrated high frequency devices require high permittivity dielectric materials with low loss as well as low sintering temperatures. Ceramics with higher permittivity (50<□
_r
<350) than conventional low temperature co-fired ceramics (5 < □
_r
< 10) will drive further miniaturization of embedded capacitor components and resonators. For microwave and mmwave frequency systems, new integration concepts will be needed to go beyond traditional packaging of electronic components as frequencies. Recently, metamaterials have been developed from composite structures with high and low permittivity. Metamaterials have the unique ability to steer microwave beams and provide unusual dielectric and magnetic properties.
