The present disclosure provides an antenna, a manufacturing method, a driving method, and an antenna system. The antenna includes: at least one group of antenna units; each group including a first antenna unit and a second antenna unit; at least one group of phase shift units, each group including a first phase shift unit coupled to the first antenna unit and a second phase shift unit coupled to the second antenna unit; and a power division transmission unit including at least one first power divider. Each first power divider includes a first end coupled to a first phase shift unit, a second end coupled to the second phase shift unit, and a third end, and a phase difference between a microwave signal transmitted from the first end to the third end and a microwave signal transmitted from the second end to the third end is a preset value.
