AWR1843BOOST: 77GHz串馈天线仿真增益

Part Number: AWR1843BOOST


我对AWR1843BOOST的单个串馈天线进行电磁仿真,仿真使用官方网站提供的pcbdoc文件尺寸参数与材料参数(AWR1843BOOST 评估板 | TI.com.cn)(www.ti.com.cn/.../sprr371)

天线基板ROGER 4835,仿真介电常数3.66,厚度4mil

贴片天线长度[38.19mil 38.19mil 36.22mil],宽度59.06mil

天线间距[48.42mil 48.43mil]

然而得到的增益方向图与用户手册不一致,仿真的增益方向图主瓣位置发生了巨大的偏移(下方左图为用户手册数据,右图为仿真数据),请问是否有问题?
