The performance evaluation of millimeter-wave antennas, which has been considered difficult in far-field measurements, can now be achieved solely through computational conversion of near-field measurements and far-field data. This eliminates the need for anechoic chambers and ultra-high precision rotators, providing a high-precision and stable measurement environment free from reflective disturbances. Furthermore, this device has been theoretically and experimentally validated after several years of research and development. - There is no influence from the propagation medium. - High-precision measurements of millimeter-wave bands, which have been considered difficult in far-field measurements, are now possible. - Absolute gain, polarization, and two-dimensional patterns can be measured, allowing for antenna diagnostics. - It employs a horizontal scanning method that allows the antenna under test to be installed horizontally. The structure makes it easy to align the antenna under test parallel to the receiving antenna. - Using the included laser displacement meter, it can automatically acquire displacement data of the tilt and unevenness of the surface of the antenna under test.
