This study proposes a method for designing and calibrating a millimeter-wave (mm-wave) multiple-input multiple-output (MIMO) antenna module. Herein, we adopt a design example involving a 64-element MIMO antenna array arranged in a triangular lattice (instead of the commonly used rectangular lattice) to achieve a 3°dB enhancement in effective isotropic radiated power. Analyzing a grating lobe diagram indicates a scan volume of ±60°/±45° in the azimuth/elevation direction. To calibrate the massive mm-wave MIMO antenna module, we propose a modified genetic algorithm to align the amplitude/phase of the transmitting/receiving signal of the module to reduce the time required for the calibration process. Finally, we conducted a simple experiment to validate the proposed method.

使用改进的遗传算法的MIMO系统中毫米波天线模块的自动校准

这项研究提出了一种设计和校准毫米波(mm-wave)多输入多输出(MIMO)天线模块的方法。在此,我们采用一个设计实例,其中包括一个布置在三角形格子(而不是常用的矩形格子)中的64元素MIMO天线阵列,以实现有效各向同性辐射功率的3°dB增强。分析光栅波瓣图可知,在方位角/仰角方向上的扫描量为±60°/±45°。为了校准大型毫米波MIMO天线模块,我们提出了一种改进的遗传算法,以对准模块的发射/接收信号的幅度/相位,以减少校准过程所需的时间。最后,我们进行了一个简单的实验来验证所提出的方法。
