Abstract

Polyester-styrene polymer composites of high permittivity ceramic nano powders (barium titanate) are fabricated and electrically measured for antenna applications. It is shown that the usage of high permittivity ceramic contents can increase the relative permittivity of the composites to around 10 at microwave frequencies. The Polyester-styrene composite material preparation technique is described. The materials are used to fabricate various dielectric resonator antenna elements. Details of the antenna fabrication techniques are discussed. Results show fabricated antenna elements and arrays with large impedance bandwidth. The presented techniques provide a precise method for fabrication of complicated or multi-segment dielectric resonator antennas.
