为了在100 GHz以上的频率精确测量天线特性，需要复杂的测量技术。这对于集成天线来说尤其具有挑战性，因为探头需要稳定、刚性的测量设置以避免损坏。本文介绍了一种天线测量装置，允许快速和可靠的三维天线方向图测量的频率范围为60 GHz至330 GHz。该系统由一个探针台，一个矢量网络分析仪（VNA）和一个工业机械臂与六轴。该机器人可确保高度可重复和精确的测量，并在扫描几何形状和分辨率方面具有高度灵活性。使用探针台，该设置不仅支持波导馈电天线的测量，而且还支持集成天线的测量。在解释了基本设置后，测量结果显示，以证明系统的能力。
In order to measure antenna properties precisely at frequencies above 100 GHz, elaborate measurement techniques are required. This is especially challenging for integrated antennas, as probes require a steady, rigid measurement setup to avoid damage. This paper introduces an antenna measurement setup that allows fast and reliable 3-dimensional antenna pattern measurements in a frequency range of 60 GHz to 330 GHz. The system consists of a probe station, a vector network analyzer (VNA) and an industrial robotic arm with six axes. The robot ensures highly repeatable and accurate measurements and allows high flexibility in terms of scan geometry and resolution. Using a probe station, this setup not only supports measurements of waveguide-fed antennas, but also integrated antennas. After explaining the basic setup, measurement results are shown to demonstrate the capability of the system.
