Abstract

This paper studies millimeter wave (mmWave) active array antennas by integrating antenna array, Anokiwave MMIC hardware and firmware design, ARM MCU, peripheral circuit design, etc. After the active array module is manufactured, the measured beam pattern is highly consistent with the simulation results of the ideal array antenna. Next, we propose a low-cost ITRI M3-Force software-defined-radio (SDR) platform to adjust the gain/phase parameters of the active array module. The measurement results validate that the parameter values are also very close to the gain/phase parameter values of the expensive network analyzer. Moreover, we measure the beam field pattern through the anechoic chamber. Based on the measured beam patterns, the proposed SDR platform adjustment has lower null pattern performance. Overall, the result provides practical and valuable validation to the antenna array module with the adjustment of ARM MCU and SDR platform.

嵌入式毫米波有源阵列天线模块设计及软件无线电平台标定

本文通过集成天线阵列、Anokiwave MMIC硬件及固件设计、ARM单片机、外围电路设计等方面对毫米波有源阵列天线进行研究。有源阵列模块制作完成后，测得的波束方向图与理想阵列天线的仿真结果高度吻合。接下来，我们提出了一个低成本的工研所M3-Force软件定义无线电(SDR)平台来调整有源阵列模块的增益/相位参数。测量结果表明，该参数值与昂贵的网络分析仪的增益/相位参数值非常接近。此外，我们还通过消声室测量了波束场方向图。基于实测波束方向图，提出的SDR平台平差具有较低的零方向图性能。综上所述，该结果对ARM单片机和SDR平台调整后的天线阵列模块提供了实用而有价值的验证。
