mAGNETIC sensing technology is of great significance in the fields of magnetic navigation, magnetic anomaly monitoring, nondestructive testing of precision devices, magnetic field measurement of biological cells, and medical nuclear magnetic resonance. In order to improve the accuracy of magnetic field measurement, superconducting quantum interferometers, magnetic resonance force microscopes and other instruments have been researched and manufactured. Although these technologies have improved the sensitivity of magnetic field measurement, they require low-temperature cooling, vacuum and other environments, which greatly limit their concrete application. In recent years, due to its unique crystal structure and energy level characteristics, the diamond NV centers has been widely used in quantum computing [1]-[4], quantum communication [5], [6], quantum precision sensing [7]-[11] and experimental research on fundamental issues of quantum physicsThe manipulation of the electron spin state in the NV centers of the diamond primarily depends on the strong coupling between the microwave field and the ground state triplet state. Various works have been proposed to provide better microwave manipulation for the NV center, including a double split-ring microwave resonator [18], microwave planar ring antenna [19], coplanar waveguide [20], broadband loop gap resonator [21]. These studies provide a solution for the realization of high-sensitivity magnetic sensing by providing a microwave field with adjustable bandwidth or a large bandwidth for strong coupling with the NV centers. However, in practical application, NV centers are distributed in the whole volume of diamond and are optically excited in the whole thickness. In addition, under the influence of different external magnetic fields, the resonant linewidth of the NV centers is distributed in the range of about 2.6-3.2 GHz, so providing a three-dimensional, broadband, and high radiation efficiency microwave field is particularly important for the coherent manipulation of the NV centers.
