摘要
各类金属载体上线天线的特性分析具有很重要的实用价值。本文运用矩量法处理各种载体上线天线问题。首先将线天线模拟为带状线,天线和载体表面均采用平面三角形单元进行剖分,RWG基函数作电流展开函数。然后介绍了线面连接处贴片单元的剖分方法,以及在连接处定义基函数和添加电压源模型。本文分析了各种形状金属载体上线天线的特性,研究了角度和位置对天线输入阻抗或辐射特性的影响。数值结果验证了方法的正确性。
The characteristics of wire antennas mounted on complex conducting objects are analyzed by using the MoM. The wire antenna is modeled as a thin strip. Planar triangular patches are chosen to discretizated the surface of the objects and the strip. RWG basis functions are used to model the surface current. Some segmentation methods for the patches near the attachment point are introduced. We define the basis functions and voltage model on the junction. Some numerical examples are introduced to analyze the characteristics of the wire antennas on conducting bodies and validate this method.
