摘要
针对以电小天线为主体的岸基甚低频发射天线辐射效率低的问题,构建了卡特勒双副天线的总体架构,研究了天线之间耦合干扰对天线电气性能的影响,提出并运用矩量法为核心的电磁数值仿真软件对两副天线进行建模,计算工作在不同状态下天线的电气参数,得出天线间距与天线耦合干扰之间的关系。验证结果表明:该方法仿真值与实际测量值一致,能有效提高天线辐射效率,由此证明了该方法的有效性和实用性。
Aiming at the low radiation efficiency of the electrically small antenna used as the main body of the shore-based VLF transmitting antenna ,this paper presents the architecture of the Cutler double antenna and researches the influence of the coupling interference between the antennas on the electrical properties of antennas .T he method of moments as the core of electromagnetic numerical simulation software is proposed to calculate the electrical parameters of the antennas working under different con-ditions and determine the relationship between the antenna spacing and the antenna coupling interfe-rence .The result shows that the proposed method is effective and practical because its simulation data agrees well with the actual measured value and it effectively improves the antenna radiation .
