Compact photonic bandgap structures in microstrip technology with reasonable physical sizes have recently been proposed as efficient frequency-band reflectors. Here, it is shown how the application of a Kaiser tapering window to the periodic pattern etched in the ground plane of the structure provides appreciable performance improvement, reducing both passband ripple and stopband attenuation and increasing bandwidth.

Abstract
Compact photonic bandgap structures in microstrip technology with reasonable physical sizes have recently been proposed as efficient frequency-band reflectors. Here, it is shown how the application of a Kaiser tapering window to the periodic pattern etched in the ground plane of the structure provides appreciable performance improvement, reducing both passband ripple and stopband attenuation and increasing bandwidth.File in questo prodotto:
