A wide-spectrum tunable Rydberg atom preparation system based on an optical frequency comb is different from a previous scheme of performing Rydberg state preparation by utilizing a single wavelength, realizes single-light-source multi-Rydberg state atom preparation by utilizing optical spectrum characteristics of the optical frequency comb, and realizes multi-light-source multi-Rydberg state atom preparation by utilizing response characteristics of different Rydberg states to a microwave electric field spectrum. An electromagnetic wave detection antenna capable of realizing wide frequency spectrum multi-frequency point and frequency point rapid switching; the atom preparation system provides a brand new technical approach for wide-spectrum electromagnetic wave detection of a microwave electric field sensor based on Rydberg atoms, and lays a technical foundation for application of the atom preparation system in the fields of spatial spectrum sensing and the like. 一种基于光频梳的宽谱可调谐里德堡原子制备系统，不同于以往利用单一波长进行里德堡态制备的方案，
