The invention provides a propeller operation monitoring device, a propeller and an airplane. The propeller operation monitoring device comprises a propeller cap, a mounting disc and an annular antenna, the propeller cap is used for being installed on a propeller hub, the propeller cap and the propeller hub are matched to form a containing cavity, and the cross section of the inner wall face of the propeller cap is circular. The mounting disc is used for being mounted on a propeller hub and located in the containing cavity, the mounting disc is in a disc shape, and the mounting disc and the propeller hub are arranged on the same rotating shaft; the mounting disc is provided with a sensor group, a main control circuit and an antenna radio frequency module, and the sensor group and the antenna radio frequency module are electrically connected with the main control circuit; the annular antenna is arranged around the inner wall face of the propeller cap, located at the position, away from the mounting disc, of the propeller cap and electrically connected with the antenna radio frequency module. The propeller is applied to the propeller operation monitoring device. The propeller is applied to the aircraft. According to the propeller operation monitoring device, the antenna circuit is not prone to being damaged in the high-speed rotation state of the propeller, and signal interference can be reduced.
