摘要:
本文介绍了一种双极化 L 波段微带阵列天线的设计思路和方法，该阵列单元采用 H 形缝隙耦合的双极化微带天线形式，阵列采用泰勒阵综合。对单元天线和阵列进行了优化设计， 并制作了实物，给出了实测结果。研制的 L 波段阵列 3dB 波束宽度≤21.64°，在波束宽度内交叉极化电平≤29.76dB，两个极化的主波束效率≥95%。
Abstract:
A dual polarized navigation microstrip array which is used in L-band is proposed in this paper. The unit uses the structure of H-slot coupling microstrip and the array is shaped by Taylor expression. Both of the antenna unit and the array are optimized and manufactured. The simulated and measured results are also given in the paper. The 3dB beam width of the L-band array is less than 21.64° and the level of cross polarization in the beam width is less than 29.76dB. Both of the main beam efficiency of the two polarizations is more than 95%.
