摘要：

A microwave (MW)-cavity antenna was designed to manipulate the spin state in diamond. It consists of an Omega antenna and a MW cavity with a thickness of 0.35 mm and a Q-value of 65. The MW intensity increased 12 times compared to that of the Omega antenna. The size of the homogeneity area is 25 pi mm(2) and the heterogeneity is less than 2.3%. Hence, more spin structures in large-sized diamonds with a high concentration can be homogeneously excited. As applied in the spin-based magnetometer, the sensitivity increased 13 times, and the noise reduced to 0.5nT/Hz(1/2). It paves the way for the development of highly sensitive spin-based sensors.
