| 摘 要： | 为适应跳频通信等宽频带系统的要求 ,设计一种仙人掌式的宽频带天线。用多端口网络理论分析该天线的阻抗特性 ,阐明该天线能够实现宽频带工作的原理。利用 Ansoft公司的 HFSS仿真工具对天线进行仿真设计 ,并对天线进行了测试 ,实测结果与仿真结果相吻合。研究了地对天线性能的影响。地的直径分别为 3 0 mm、2 0 0 mm、3 0 0 mm时 ,该天线 VSWR小于 2的相对阻抗带宽超过 3 4%。地对天线辐射方向图有着显著影响 ,通过选择地的大小可以获得所需的方向图

| Abstract: | The design of a novel Vertical polarized antenna for wide band systems,named the Cactus Antenna,is described in this paper.The impedance characteristics of the cactus antenna are analyzed,and the principle of the cactus antenna working well over wide frequency band is explained.The simulation of the design of the cactus antenna is performed with the HFSS simulation tools,and a experiment on the actual cactus antenna is performed too.The experimental results accorded with the simulation results well.The characteristics of the cactus antenna are affected remarkably by the size of ground plane. Desired patterns can be achieved by selecting the appropriate size of the ground plane. |
