This invention discloses a flexible microwave radiator and magnetic detection system for magnetic detection of NV centers in diamond. The flexible microwave radiator includes a flexible dielectric substrate and a conductive layer disposed on the substrate. The conductive layer is patterned to form a power supply area and a radiation area electrically connected to the power supply area.
