Transmitarray antennas with dual-band and dual-polarization capabilities are studied here numerically. The antennas are designed based on linearly-polarized unit-cells working at Ka-band for satellite applications. The unit-cells include two printed patches and a connecting via; a 180° phase shift is obtained by rotating one of the patches. The dual-band property is achieved by interleaving unit-cells dedicated to each band, and two different polarizations in each band. The numerical results demonstrate the working principles of dual-band dual-polarized transmitarrays. © 2017 Euraap.
