【摘要】 基于弗洛奎定理给出了一种计算无限相控阵有源单元方向图的方法。与传统的基于有源反射系数的方法不同,这种方法不但可以用于计算功率方向图,而且可以计算场方向图,因此可以计算诸如交叉极化、相位信息等更多的辐射特性。通过数值计算结果与仿真结果的比较验证了方法的正确性。更多还原

【Abstract】 Based on the Floquet’s principle,methods of determining the active element pattern of infinite phased array antennas were proposed,comparing with the comventional method,the method can be used to not only calculate the active element power pattern but also calculate the active element field pattern.So more radiation information such as cross-polarization levels,phase information can be obtained.The comparison between numerical results and simulation results shows these methods are feasible.更多还原
