摘要
将四维天线阵的时域激励进行频域等效,并采用传统的频域全波分析方法分析了四维天线阵的辐射特性。计算了具有时间调制特性孔径尺寸可变以及具有运动相位中心特性的两种印刷偶极子四维天线线阵的辐射特性,结果与已有文献报道的实验结果吻合良好。为四维天线阵的精确分析与设计提供了重要的参考依据。
In this paper, time-domain excitations of four dimensional antenna arrays are decomposed into frequency-domain equivalent excitations, and the conventional frequency domain full-wave simulation approach is used to simulate its radiation characteristics. The time modulated variable aperture sized linear arrays and the moving phase center linear arrays are simulated, and the simulation results are in good agreement with published measurement data, thus providing an important ref- erence to the precise analysis and design of the four dimensional antenna arrays.
