Dual-Linearly Polarized Unit-Cell and Transmitarray at Ka-Band

Abstract : This paper presents the design and performance of a narrow-patch wide-band unit-cell used for dual-linearly polarized transmitarray with 3-bits of phase resolution and a small lattice periodicity (0.36x lambda(0) at 29 GHz). The polarizations of transmitting and receiving layers of the unit-cell are orthogonal, leading to a negligible spill-over contribution of feeding source to the co-polarized pattern of the transmitarray. The insertion loss is smaller than 0.5 dB at 29 GHz for all phase states. A dual-linearly polarized transmitarray is designed and analyzed to validate the interleaving technique for dual-polarization operation. A good agreement between single-polarized and dual-polarized transmitarrays is observed, thus validating almost perfect independence of both polarizations.
