摘要
设计了一种空域变极化微带天线,他是通过同时激励起两种工作模式一起工作来实现的,这两种模式产生的电磁波在空间上方向图互补,极化相互正交。计算结果表明,这种天线可以在工作频带范围内满足空域变极化的目的。这种天线设计制作方便简单,变极化效果明显,并且仅由扫描角就可以控制极化变化,为变极化天线阵的设计和空域变极化理论的应用提供了理论基础和参考依据。
This article designs a type of microstrip antenna with spacial variable polarization. Its realization is based on two modes with orthodoxy polarization and beam compensating. Theoretical analysis shows that this kind of antenna can satisfy the aim of the spacial variable polarization in the frequency bandwidth. This type of antenna has got advantages of convenient design,obvious effect of variable polarization and polarization changing with the scan- angle only,which provides theory and references of both variable polarization antenna design and spacial variable polarization theory.
