Zusammenfassung:	The embodiment of the invention provides a liquid crystal phase shifter, a preparation method thereof and a liquid crystal antenna system. The liquid crystal phase shifter comprises at least one liquid crystal unit group, each liquid crystal unit group comprises a first liquid crystal unit and a second liquid crystal unit which are stacked in the thickness direction of the liquid crystal phase shifter, and a connecting layer arranged between the first liquid crystal unit and the second liquid crystal unit, the first liquid crystal unit and the second liquid crystal unit are connected through the connecting layer; and the feed structure comprises at least one feed unit, the feed units and the liquid crystal unit groups are arranged in a one-to-one correspondence manner, and the feed units are configured to feed the liquid crystal unit groups. According to the liquid crystal phase shifter provided by the embodiment of the invention, the plane space occupied by the liquid crystal phase shifter is saved, the mini
