摘要: 本文对采用不同极化单元的顺序旋转阵列进行了研究。顺序旋转阵列可以采用线极化或圆极化贴片作为单元，且不同极化特性的单元对阵列性能有着不同的影响，这里分别利用线极化单元和圆极化单元顺序旋转组阵，构成2 × 2阵列，研究了两种阵列的带宽及增益等性能。结合理论分析与仿真结果，得出结论：两种阵列均能很好地展宽带宽，而采用线极化单元顺序旋转组阵的增益要比采用圆极化单元少将近3 dB，但是前者的增益带宽要更宽。最后研究了采用不同极化单元时顺序旋转阵列间距对阵列性能的影响，分析了最优间距的获取。
Abstract: Sequentially-rotated (SR) arrays with elements having different polarization properties are studied in this paper. Linearly-polarized (LP) or circularly-polarized (CP) patches can both be used as elements of SR arrays, and have different effects on array performance. Two 2 by 2 SR arrays are constituted by LP and CP elements, respectively. Then, the bandwidth and gain performances of two arrays are studied. Theoretical analysis and simulation research are conducted. It is demonstrated that the arrays can broaden the bandwidth significantly. However, the gain of the SR array with LP elements is about 3 dB lower than that with CP elements, but gain bandwidth of the former array is wider. Finally, effects of the element spacing on SR arrays are studied with different polarized elements and the optimal spacing selection is analyzed.
