利用Ansoft HFSS软件,以带有平板反射器的单极子柱状扇形天线为研究对象,通过对比单层罩结构和B夹层罩结构对天线电性能影响的异同,分析了天线谐振频率,远场区辐射和带宽随罩壁厚度,天线罩内径以及夹芯层占罩壁总厚度之比例等参数的变化趋势,找出了以上参数对带宽影响的最优化范围,在半功率波束改变不大的情况下,B夹层天线罩具有单层罩近2倍的带宽。
Ansoft HFSS software was used to study the monopole cylindrical sector antenna with flat reflector. By comparing the similarities and differences between the single-layer cover structure and the B-sandwich structure on the electrical performance of the antenna, the resonant frequency of the antenna, Radiation and bandwidth with the thickness of the cover, the diameter of the radome and the ratio of the sandwich layer to the total thickness of the wall thickness and other parameters of the trend, to find out the above parameters on the bandwidth of the optimization range, the semi-power beam changes little The B mezzanine radome has nearly twice the bandwidth of a single-layer cover.
