| 摘 要： | 针对波导缝隙阵列，提出了一种基于复数电压分布的改进的波导缝隙阵列天线的设计方法。 针对Elliott 对于波导缝隙阵列的设计只适用于实数的电压分布，从而不能设计出有任意形状的方向图的天线的问题，对此方法进行了改进，将其扩展到了任意的复数电压分布，并且考虑了缝隙之间互耦的影响。最后，利用改进的方法设计了一个有16个缝隙的端馈线阵方向图，与商业软件Ansoft HFSS的仿真结果比较，证明了方法的有效性。

| Abstract: | This paper proposes an improved design method of slotted waveguide antennas.Since Elliott's design method for slotted waveguide antennas applies only to the case with real voltage distribution it is incapable of designing slotted waveguide antennas with arbitrary radiation pattern.The improved design method presented and is extends its applications to case of the complex voltage distribution including the effects of mutual coupling.The comparison of results derived by the improved method and the commercial ... |
