摘要
为了分析多馈源天线,采用矢量三角形基函数的矩量法求解天线积分方程。介绍了分析线天线所采用的基以及求解过程,对一种带状偶极子天线模型进行数值计算。研究了共模和差模两种馈电模式下,天线的电流分布以及频率特性。计算结果表明,双馈偶极子具有较小的回波损耗、宽频带以及双频工作等优点。
To analyze the muhimode feed antennas, the integral equation of the antenna is solved by using a method of moment with vector triangle basis function. The basis of wire antenna analysis is introduced, as well as the discussion of solving equation procedure. After that, a dipole antenna model with belt form is simulated by using proposed method, and the current distributions and frequency characteristics of this model have been investigated in case of common- and different-mode feed. Numerical results show that the double-feed dipole antenna has the advantage of smaller returningloss, wider band, and dual-frequency, etc.
