In this contribution different dual-linear polarization elements for reflectarrays are proposed with the aim of achieving more than one cycle of 360º of phase delay for both polarisations, with low cross-polarisation levels, enough room for adding control devices and a linear phase response in the two bands, one from 10.70 GHz to 12.75 GHz (Rx) and the other from 14.00 GHz to 14.50 GHz (Tx). The elements are based on two stacked patches aperture-coupled to delay lines, in order to provide a good response in both bands. The simulations results show acceptable performances in phase range, bandwidth and cross polarisation.

Abstract
In this contribution different dual-linear polarization elements for reflectarrays are proposed with the aim of achieving more than one cycle of 360º of phase delay for both polarisations, with low cross-polarisation levels, enough room for adding control devices and a linear phase response in the two bands, one from 10.70 GHz to 12.75 GHz (Rx) and the other from 14.00 GHz to 14.50 GHz (Tx). The elements are based on two stacked patches aperture-coupled to delay lines, in order to provide a good response in both bands. The simulations results show acceptable performances in phase range, bandwidth and cross polarisation.File in questo prodotto:
