Title:
WAVEGUIDE PROBE STRUCTURE, AND CALIBRATION DEVICE AND CALIBRATION METHOD FOR ANTENNA ARRAY
Document Type and Number:
WIPO Patent Application WO/2024/065177
Kind Code:
A1
Abstract:
The present disclosure belongs to the technical field of antennas. Provided are a waveguide probe structure, and a calibration device and a calibration method for an antenna array. The waveguide probe structure of the present disclosure comprises a waveguide-to-coaxial converter, a tapered waveguide and a first straight waveguide, wherein the waveguide-to-coaxial converter is configured to transmit and receive two orthogonal linearly polarized signals; the tapered waveguide is provided with a first waveguide cavity, which is provided with a first waveguide port and a second waveguide port that are arranged in the lengthwise direction of the first waveguide cavity; the first waveguide port is connected to the waveguide-to-coaxial converter; the second waveguide port is connected to the first straight waveguide; the dimension of the cross section of the first waveguide cavity is monotonically increased in a direction in which the first waveguide port points to the second waveguide port; the first straight waveguide is provided with a second waveguide cavity; and the dimension of the cross section of the second waveguide cavity is equal to the dimension of the second waveguide port.
