| 摘 要： | 带宽是移动通信加罩天线的一项重要技术指标。利用A nsoft HFSS软件,以单极子柱状天线为研究对象,首先对单层罩结构进行仿真,其结果验证了方法的正确性;并在此基础上提出一种新型的B夹层罩壁结构,分析了天线谐振频率和带宽随罩壁厚度,材料的介电常数,天线罩内径以及夹芯层占罩壁总厚度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,设计的这种天线罩具有单层罩近2倍的带宽。

| Abstract: | The monopole rod antenna is studied by using the software of Ansoft HFSS.Firstly,the single layer radome is simulated and results confirm the correctness of this kind of the simulation method.Secondly,one novel B-sandwich radome structure is proposed.The variation tendency of the resonance frequency and the bandwidth depended on a series of parameters is analyzed the parameters include the total depth of the radome,the permittivity constant of the dielectric interlayer material,inner radius,and the scale of the interlayer depth to the total radome one.Optimal ranges of these parameters for the bandwidth are found out.The result shows that this kind of radome has the doubled bandwidth of the single layer radome. |
