| 摘 要： | 首先对天线阵列获得最大功率增益时的最优激励问题进行了理论推导;然后给出了天线阵列的增益与方向函数;最后以对数周期天线为例,利用Mat lab语言编程计算了不同波束指向上最大功率增益所需的激励,得到了最优激励时阵列的各种电参数。所得结果表明:最优激励下的阵列具有更好的电性能,据此建立的最优激励与最大功率增益的数据库,可方便地用于对对数周期天线阵的深入研究中。

| Abstract: | Firstly, the optimized excitation about the maximum power gain of antenna arrays is theoretically deduced. Then the gain of the antenna arrays and the direction function are given. Finally taking the log-periodic dipole antenna (LPDA) as an example, and using Matlab language program, the excitation of the maximum power in different directions of the beam is calculated and different electrical parameters of the array are obtained. The result shows that the array under the optimized excitation is proved to have better capability. The database of the optimized excitation and the maximum power gain is established and can be used in the further study of the LPDA arrays conveniently. |
