Composite defect-mode superstructures and wideband EBG resonator Antennas

Abstract

We propose two electromagnetic band gap (EBG) structures made out of multi-layer dielectric slabs to enhance the bandwidth of EBG resonator Antennas (ERAs). These multi-layer structures are designed to achieve wide defect-mode bandwidths. Wide defect modes are created by optimising the permittivity and thickness of the individual slabs, as well as the inter… (More)
