Data Source: Measured data collected during the research on the entire array prototype and third-party test reports.
Dataset Content: Includes original radiation pattern test data for each assessment indicator specified in the technical requirements of the entire array prototype, third-party test reports, corresponding supporting documents, 8 published academic papers, and 3 granted patents.
Data Volume: 132 MB.
Generation Method: Tests were carried out in an indoor antenna anechoic chamber environment, referencing the standard GB/T 40602.2-2021 *Radio Disturbance of Antennas and Receiving Systems - Part 2: Fundamental Measurements - Indoor Planar Near-Field Measurement Methods for High-Gain Antenna Radiation Patterns*.
Test Equipment: Vector network analyzer (model: R&S ZNA) and anechoic chamber planar near-field test system.
Testing Procedures: 1. Connect the phased array under test to the anechoic chamber planar near-field test system, set the distance between the scanning probe movement plane and the radiating surface of the phased array antenna under test to 3 to 5 wavelengths, then power on and preheat to stabilize both the test system instruments and the phased array under test. 2. Connect the RF beam ports of the antenna under test to the vector network analyzer of the anechoic chamber planar near-field test system. 3. Configure the measurement frequencies of the vector network analyzer to 27.5 GHz, 28.7 GHz, 29.9 GHz, and 31 GHz. 4. Control the beam pointing direction of the antenna under test via the upper computer, and run the scanning measurement system using the near-field test software. 5. Record and save test data including radiation patterns, polarization modes, directivity coefficients under different beam pointing directions, as well as axial ratio and side lobes in the normal direction. 6. Fix the antenna under test in a stationary position, use a tape measure to measure the diagonal dimension of the rectangular-arranged array of the antenna under test, where the diagonal length of the array is taken as the antenna aperture.
