双锥共线阵天线因其宽频带,高辐射功率等特点被广泛应用于工程中,文中采用基于有限元法的电磁场仿真技术对 双锥共线阵天线进行辐射特性研究,分别通过改变阵子个数,锥角等参数研究其辐射特性与各参数变化的关系。然后根 据导航设备的实际需要设计出一种满足国际民用航空公约附件十要求的双锥共线阵天线,实验结果表明,该天线适用于 陆基导航系统中测距机的信标天线。

Linear biconical antenna array is widely used in engineering application because of its directive characteristics and high radiation power. In this paper, by means of the HFSS simulation technology based on the finite element method, the radiation characteristics of linear biconical antenna array are studied. and the simulation results of the radiation patterns are given by changing the element number of array and its cone respectively. According to the antenna requirements for Distance Measuring Equipment (DME), a linear biconical antenna array is designed, which meets the specifications recommended by International Civil Aviation Organization Annex 10.
