摘　　要：以相控阵天线为代表的下一代通信基站天线正在向着高频段、高增益、高密度、高指向精度方向发展,机械结构因素对通信系统信道质量的影响与制约越来越明显、机电耦合问题越来越突出.为有效保证复杂环境下5G/6G通信容量目标的实现,本文针对通信基站相控阵天线的机电热耦合问题,建立了融合阵元位置偏移、姿态偏转及温度分布等因素的基站天线信道容量机电耦合模型,可据此快速评估射频器件发热环境下通信指标退化情况;构建了阵列天线电场强度与信道容量对阵元随机位置误差的灵敏度模型,分析比较了不同工作条件下各阵元随机位置误差对通信指标的影响规律.The next generation communication base station antennas represented by the phased array antennas are developing towards high frequency,high gain,high density and high pointing accuracy.The influence of mechanical structure factors on the channel quality of communication system is becoming more and more obvious,and the electromechanical coupling problem is becoming increasingly prominent.In order to ensure the realization of 5G/6G communication capacity in complex working environment,the electromechanical coupling model of channel capacity was established in terms of the electromechanical-thermal coupling problem of the communication base station phased array antenna.Several factors such as the positional shift,deflection of the antenna element and temperature distributions were considered in this model,which can be used to assess the degradation of communication indicators in the heating environment of RF devices.A sensitivity model of the array antenna’s electric field strength and channel capacity to the random position error of the antenna element was constructed,and the effect of random position error of each antenna element on the communication indicators under different working conditions was analyzed.
