The invention discloses a four-blade circularly polarized antenna propeller. The four-blade circularly polarized antenna propeller comprises a propeller hub mounted on the aircraft; four blades are mounted on the propeller hub, a balun is nested in the propeller hub, two grooves are symmetrically formed in the upper part of the balun, a group of long half-wave symmetrical dipole antennas and a group of short half-wave symmetrical dipole antennas are symmetrically mounted on the upper part of the balun, and the long half-wave symmetrical dipole antennas and the short half-wave symmetrical dipole antennas are arranged in the blades of the propeller hub; and a radiation plate is arranged at the lower part of the balun, an impedance converter is arranged at the bottom of the balun, and the long half-wave dipole antenna, the short half-wave dipole antenna, the balun, the radiation plate and the impedance converter jointly form a self-phase-shift orthogonal half-wave dipole circularly polarized antenna. The four-blade circularly polarized antenna propeller is reliable in performance and simple in structure, saves the space of an aircraft installation part, meets the requirement that equipment converts the power of an engine into driving force, and achieves good communication performance.
