Abstract
A waveguide probe structure, a calibration device for an antenna array and a calibration method for an antenna array are provided. The waveguide probe structure includes a waveguide coaxial converter, a tapered waveguide and a first straight waveguide. The waveguide coaxial converter is configured to transmit and receive two orthogonal linearly-polarized signals; the tapered waveguide includes a first waveguide cavity including a first waveguide port and a second waveguide port, the first waveguide port is connected to the waveguide coaxial converter, the second waveguide port is connected to the first straight waveguide, and a size of a cross section of the first waveguide cavity increases monotonically in a direction from the first waveguide port to the second waveguide port; the first straight waveguide includes a second waveguide cavity, a size of a cross section of the second waveguide cavity is equal to a size of the second waveguide port.
