A liquid crystal phase-shifting unit includes a first conductive substrate, a second conductive substrate disposed parallel to the first conductive substrate, and a liquid crystal layer disposed between the first conductive substrate and the second conductive substrate. A distance between the first conductive substrate and the second conductive substrate is defined as a liquid crystal cell thickness, which is less than or equal to 5 μm. The liquid crystal layer includes a cholesteric liquid crystal, which has a pitch. The ratio of the liquid crystal cell thickness to the pitch is greater than or equal to 1. An antenna module including the liquid crystal phase-shifting unit is also provided.
