| 摘 要： | 分析了GPS微带天线阵列阵元间的互耦特性,得出了满足互耦要求的合适的最小阵元间距;设计了一种小型四阵元GPS微带偏振天线阵列,该阵列采用传统右圆极化阵元舜口双线性极化阵元相结合,使得相同阵元的天线阵列的自由度提高;从仿真的结果可以看出,在不增加阵列面积的情况下,该阵列能够在干扰方向产生比传统微带天线阵列更深的零陷,很大程度地提高了阵列的抗干扰性能;最后给出了GPS微带双频偏振层叠天线的一些重要的设计参数.

| Abstract: | Analyzed the mutual coupling of GPS arrays' elements;designed a small four elements GPS polarimetric arrays,this arrays combined the right-hand circularly polarized(RHCP)elements and dual-linearly polarized elements,increased the degrees of freedom of arrays at the same elements number;from the simulation results,can find that the arrays' performance of anti-jamming is improved greatly than traditional microstrip antennas;in the end,many design parameters of a compact GPS dual-frequency,dual-polarization st... |
