Abstract

In this paper, simple, low cost, and convenient automatic antenna measurement system is proposed to obtain the antenna measuring parameters such as, radiation pattern, gain, Half Power Beam Width (HPBW) and maximum power for RF/microwaves antennas and antenna arrays within the frequency range of 700MHz to 20 GHz. The system consists of nema-23 stepper motor, Arduino, and R&S ZVB20 Vector Network Analyzer (VNA). All the necessary hardware is synchronously controlled by LabVIEW. The stepper motor moves with the increment of 1.8 degree and cover 360-degree rotation using LabVIEW software and Arduino control system. The receiving AUT is connected to VNA and the VNA is linked to LabVIEW via GPIB interface. The VNA measures the power received by AUT after each rotation step and real time radiation pattern is plotted on the GUI of LabVIEW. The measured results of proposed system are in good agreement with the expected results. This portable system can be used in both commercial and education sector.

宽带天线测量软硬件平台的开发

本文提出了一种简单、低成本、方便的天线自动测量系统，用于700MHz ~ 20ghz频率范围内射频/微波天线和天线阵列的辐射方向图、增益、半功率波束宽度(HPBW)和最大功率等天线测量参数的获取。该系统由nema-23步进电机、Arduino和R&S ZVB20矢量网络分析仪(VNA)组成。所有必要的硬件由LabVIEW同步控制。采用LabVIEW软件和Arduino控制系统，实现步进电机以1.8度的增量移动，实现360度旋转。接收AUT与VNA连接，VNA通过GPIB接口与LabVIEW连接。VNA测量每个旋转步骤后AUT接收的功率，并在LabVIEW的GUI上绘制实时辐射方向图。系统的实测结果与预期结果吻合较好。这种便携式系统可用于商业和教育部门。
