A single layer reflectarray configuration is investigated to achieve a dual-polarization operation mode, at millimetre-wave frequencies. The reflectarray cell is proposed as a viable solution for future implementations of passive reflecting surfaces for 5G applications. The proposed configuration offers independent phase tuning in each polarization, a very thin structure (= 0.0237X, at/=28 GHz), and small cell sizes (= (SAX at/=28 GHz), thus preserving the ability to focus the main beam at large scan angles. A dual-polarized reflectarray prototype is preliminarily designed and numerically tested, demonstrating the ability of the unit cell to provide independent radiation characteristics for each polarization.

Abstract
A single layer reflectarray configuration is investigated to achieve a dual-polarization operation mode, at millimetre-wave frequencies. The reflectarray cell is proposed as a viable solution for future implementations of passive reflecting surfaces for 5G applications. The proposed configuration offers independent phase tuning in each polarization, a very thin structure (= 0.0237X, at/=28 GHz), and small cell sizes (= (SAX at/=28 GHz), thus preserving the ability to focus the main beam at large scan angles. A dual-polarized reflectarray prototype is preliminarily designed and numerically tested, demonstrating the ability of the unit cell to provide independent radiation characteristics for each polarization.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
