The invention mainly belongs to the technical field of antennas and relates to a fast agile multi-functional planar and quasi-three-dimensional antenna, in particular to a reconfigurable multi-functional antenna. The multi-function antenna is composed of the semiconductor plasma and the fast, large current, simple TFT matrix driving technology distributed direct drive arrays integrated into silicon, glass, sapphire, silicon carbide and other planar or curved dielectric substrates, the multi-function antenna can quickly, dynamically control the shape, size and the correct position to be in of the radiating elements constituting the planar array, the antenna frequency is reconfigurable, polarization reconfigurability, beam control and gain agility reconfigurability, sidelobe position and relative level reconfigurability, and combinations of these, like a two-dimensional printer, rapidly and agilely change the antenna from one function to another, transforming a planar or quasi-three-dimensional antenna into a multi-function planar or quasi-three-dimensional antenna.
