| 摘 要： | 一般情况下,蜂窝通信基站、机场导航广播基站等系统中采用的天线要求全向方向,较高增益,较宽带宽等多项指标。针对该应用背景,在传统的COCO天线的基础上,提出了一种结构特殊的高阻抗高效率全向CO-CO天线模型,采用HFSS建立了仿真模型,通过仿真优化,给出了具有高效率、高阻抗、低驻波、较宽带宽的设计结果,进一步设计了该型天线样品,暗室增益测试和驻波测试表明,所设计的改进型COCO天线完全达到了设计目标。

| Abstract: | Generally,many antennas used in many communication base stations and airport navigation broadcast base station are required to be omni-directionas,high gain and proper wide bandwidth.Based on the application background,a new kind of coaxial collinear(COCO)antenna with special structure,higher efficiency and higher impedance compared with the traditional one is presented here.Furthermore,a simulation model with respect to the antenna is created in the HFSS system and the simulation result shows that it is high efficient,high impedance,low VSWR and proper wide bandwidth after making optimization,which could be applied for the above mentioned systems very well.Last,a sample is developed and tested in an anechoic chamber.The test results show well consistent with the simulation ones. |
