1. A phased array antenna system, comprising:
a feed structure and at least one phased array antenna element, wherein the at least one phased array antenna element comprises a first impedance transformation unit, a micro electromechanical system (MEMS) phase-shifting multi-unit and an antenna;
the first impedance transformation unit is connected to the feed structure, and the MEMS phase-shifting multi-unit is connected between the first impedance transformation unit and the antenna;
wherein the at least one phased array antenna element further comprises a second impedance transformation unit connected between the MEMS phase-shifting multi-unit and the antenna.
