| 摘 要： | 提出一种新型的CTS(Coaxial Transverse Stub)阵列天线—CCTCS(Coaxial Continuous Transverse Conical Stub)阵列天线。天线由串联馈电单元组成,各单元采用圆锥状同轴开槽结构,具有成本低、易加工和易调节的特点。设计一个十单元的阵列天线模型,并通过有限积分数值方法对该阵列计算仿真,结果表明,相对于传统的CTS阵列,CCTCS阵列在满足全向性、低驻波、垂直极化和阻抗匹配的同时,工作带宽和旁瓣电平都有较好的改善。

| Abstract: | A new type of CTS(Coaxial Transverse Stub) antenna array-Coaxial Continuous Transverse Conical Stub(CCTCS) antenna array is presented in this paper.This type of antenna,which is based on the conical linear coaxial structure,is constructed by several series-fed elements.It provides preferable performance of low cost,easy to be fabricated and adjusted.A ten-element prototype is designed,and the FIT(Finite Integral Technology) is used to simulate these arrays.The result indicates that compared to the traditional CTS array,the CCTCS array can not only meet the requirements of omni-directional,low-VSWR(Voltage Standing Wave Ratio),perpendicular polarization and impedance matching simultaneously,but also,provide much better performance of the bandwidth and the side lobes. |
