高方向性天线或使用大型天线阵列的各种波束成形技术有望被采用以克服毫米波段上的严重路径损耗。本文研究了天线波束宽度对毫米波信道特性和建模的影响。使用宽带信道探测器在28和38 GHz频带中进行室内信道测量活动。从实测数据中提取了与天线波束宽度相对应的均方根时延扩展和到达角扩展等大尺度参数。最后，我们推导出经验信道参数，并观察天线波束宽度的依赖性。
Highly directive antennas or various beamforming techniques using large antenna arrays are expected to be adopted for overcoming the severe path loss on millimeter-wave bands. This paper investigates the effect of antenna beamwidth on millimeter-wave channel characterization and modeling. The indoor channel measurement campaigns were performed using a wideband channel sounder in the frequency band of 28 and 38 GHz. The large-scale parameters such as root mean square (RMS) delay spread and angular spread of arrival corresponding to the beamwidth of antenna are extracted from measured data. Finally, we derived empirical channel parameters and observed the dependency of antenna beamwidth.
