A single-layer dual-band/dual-polarized reflectarray configuration is investigated for emerging 5G systems. A unit cell able to operate independently at two distinct frequencies within the Ka-band (28/38 GHz), in a dualpolarization mode, is designed by adopting two pairs of miniaturized fractal patches. The proposed cell allows to achieve an independent optimization of the phase at each frequency and polarization, showing negligible mutual coupling effects between the two bands. A reflectarray prototype is simulated demonstrating its ability in achieving arbitrary beam directions at each frequency, for both polarizations. Due to its compactness and versatility, the proposed unit cell is appealing for future 5G applications.

Abstract
A single-layer dual-band/dual-polarized reflectarray configuration is investigated for emerging 5G systems. A unit cell able to operate independently at two distinct frequencies within the Ka-band (28/38 GHz), in a dualpolarization mode, is designed by adopting two pairs of miniaturized fractal patches. The proposed cell allows to achieve an independent optimization of the phase at each frequency and polarization, showing negligible mutual coupling effects between the two bands. A reflectarray prototype is simulated demonstrating its ability in achieving arbitrary beam directions at each frequency, for both polarizations. Due to its compactness and versatility, the proposed unit cell is appealing for future 5G applications.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
