| 摘 要： | 针对TLM细线模型提出一种馈电方法,使得模型可用于计算线天线的端口特性。采用电压源激励,馈电点可位于细线模型的中心或者两个细线模型之间,分析得出相应的馈电点处的电流计算公式。采用馈电方法下的TLM细线模型仿真计算振子天线的输入阻抗,误差分析表明计算结果具有很好的精度,从而证明了馈电方法的有效性。馈电方法下的TLM细线模型可用于各种线结构端口特性的求解,具有实际意义。

| Abstract: | A feed method is presented for the thin-wire model of transmission-line matrix(TLM) method.With this method,the TLM thin-wire model can be used to calculate the port properties of wire structure.The voltage source is used in this method,and the feed point current is derived from the equivalent circuit.In the simulation,the input impedance of wire antenna is calculated using the TLM thin-wire model combined with the feed method proposed in this paper.The results have good accuracy compared with the data in t... |
