本文详细介绍了一种自动毫米波天线测量装置，并给出了标准增益喇叭天线和280 GHz集成天线的增益和指向性测量结果。该装置包括一个矢量网络分析仪（VNA）和不同频段的变频器，一个六自由度工业机器人，以及一个提供接口和控制测量的控制器。这种设置使得在60 GHz和330GHz频率范围内高精度地测量波导馈电和集成芯片天线的增益、指向性、辐射功率和效率成为可能。此外，该设置是高度可配置的。在AUT（被测天线）周围的任意平面上的任意轨迹可以快速测量，而无需改变任何硬件。
In this paper a detailed description of an automated mm-wave antenna measurement setup is given, and gain and directivity measurement results are shown for a standard gain horn antenna and an integrated antenna at 280 GHz. The setup comprises a vector network analyzer (VNA) with frequency converters for different frequency bands, a six degree of freedom industrial robot, and a controller that provides the interface and controls the measurements. This setup makes it possible to measure gain, directivity, radiated power, and efficiency of both waveguide fed and integrated chip antennas at frequencies between 60 GHz and 330GHz with high accuracy. Furthermore, the setup is highly configurable. Arbitrary trajectories on arbitrary planes around the AUT (antenna under test) can be measured quickly without having to change any hardware.
