采用动量方法对螺旋形天线进行了高效率的分析。将电场积分方程和动量方法相结合解算出天线的电流。脉冲测试函数和螺旋天线轮廓精确匹配。在整个分析过程中采用了细线近似,天线设定为沿z轴方向。对细线近似和delta带隙源进行了描述。数值结果显示了该方法的有效性和精确性。
The momentum method is used to analyze the helical antenna with high efficiency. The electric field integral equation and the momentum method are combined to calculate the antenna current. The pulse test function exactly matches the helical antenna profile. A thin line approximation was used throughout the analysis and the antenna was set along the z axis. Thin line approximation and delta band gap sources are described. Numerical results show the effectiveness and accuracy of this method.
