WebOct 1, 2016 · The proposed hybrid antenna system consists of a D = 50 cm offset parabolic-cylindrical reflector with f/D = 0.4 fed by an 8 × 4 dual linear-polarized stacked patch phased array antenna placed ... WebIn this study, we reveal a novel aerial display system, to the best of our knowledge, that combines volume hologram mirrors with a dihedral corner reflector array (DCRA). The suggested aerial display has a see-through capability, which allows for a new design of aerial displays by combining with other types of displays.
