An axial ratio compensation method performed by an antenna system including an antenna array having antenna elements is provided. The axial ratio compensation method includes: when first ports of the antenna elements are excited, controlling phases at the first ports according to first beamforming information for driving the antenna array to generate a first linearly polarized beam according to a predetermined direction; when second ports of the antenna elements are excited, controlling phases at the second ports according to second beamforming information for driving the antenna array to generate a second linearly polarized beam according to the predetermined direction; compensating at least one of a phase difference an electric field magnitude difference between the first and second linearly polarized beams to compensate an axial ratio of a predetermined circularly polarized beam directed toward the predetermined direction.
