新型CTS阵列天线的设计及仿真

Design and Simulation of the New Type of CTS Array

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。
