| 摘 要： | 探讨了应用于单极子天线设计的圆柱体近似方法。主要阐述了1种用等效面积法设计超宽带（UWB）天线的方法,并仿真设计了一款抛物闭合面曲面的UWB天线。与传统方法相比,大大降低设计费用和计算量,且易于工程实现。通过仿真的阻抗带宽和辐射方向图,发现该方法设计的天线在整个带宽内辐射方向图比较一致,且有较好的全向辐射特性。

| Abstract: | In this paper,a method of cylindrical approximation in designing monopole antenna is discussed.First,designing monopole ultra-wideband（UWB） antenna using a method of equivalent area is presented.A closed surface with a parabola curve and exponential curve UWB antenna is simulated.Compared with conventional designing method,the method of equivalent area reduces greatly the design cost and the computation and can be used in engineering practice.Then,the impedance bandwidth and the radiation pattern of the antenna are obtained by simulating.It has been found that the antenna has good bandwidth and radiation pattern in the entire bandwidth and has a better omni-directional radiation characteristic. |
