摘要
针对对数周期天线作为阵元,可以实现在空间上合成大功率的目的.利用微波网络理论与矩量法相结合,系统地分析、计算了单个对数周期天线的输入阻抗、增益及方向特性与其张角的关系,分析了扇形阵列的电特性与单元天线之间张角的关系;所得结果在天线组阵中对单元天线的合理选择与布局有着重要的指导意义.
Using LPDA as cells, we can get high power in extensity. The input impedance, gain and directivity of a log-periodic dipole antenna are analyzed and calculated systematically by the method of moment and network theory of microwave. Also, the relation between the electric character and the angles are analyzed. And the results obtained can be instructional on design of LPDA arrays.
