Abstract Details

2020, Master of Science, Ohio State University, Electrical and Computer Engineering.
The characterization of antenna radiation patterns in millimeter-wave (mmW) bands can be particularly challenging. There are several reasons for this, but one of the most significant is that the misplacement of just a few millimeters of the probe antenna can generate substantial errors in the pattern measurement result. To overcome this, a highly precise measurement system that incorporates a FANUC 6-axis small robotic arm is implemented. System testing shows a positional accuracy and repeatability of approximately 20 μm. After the system is implemented, programmed, and tested, pattern measurements are done on three different millimeter-wave antennas. By characterizing the radiation pattern of a V-band horn antenna, it is demonstrated that far-field measurements can be performed accurately with the robotically controlled system. Furthermore, the characterization of the center element pattern of a 60 GHz phased array has shown that the measurements with the system are repeatable as well. Additionally, it is demonstrated that the system can perform near-field measurements by successfully characterizing a U-band horn antenna with a planar scan. The instrumentation, testing methodology, results and challenges are reported.
