摘要
文章提出了一种单膜片极化扭转波导,与常规扭波导相比具有体积小和重量轻等优点,其厚度只有1/4波长。文章首先应用电磁场理论,对2个不连续性的感性面进行分析,得到了单膜片极化扭转波导的散射矩阵;然后采用Ansoft HFSS进行仿真,并对单膜片极化扭转波导厚度进行了优化;最后通过实测表明,实测结果与仿真值基本一致。该单膜片极化扭转波导有较小的驻波和插入损耗,可以满足工程需要。
A type of single patch polarization twist waveguide is presented in this paper. Compared with general twist waveguide, it has the advantages of small size and light weight. The thickness of patch is only a quarter wavelength. Firstly, two discontinuity inductive surface is analyzed using the theory of electromagnetic fields to obtain scattering matrix of the sin-gle patch polarization twist waveguide. Then using Ansoft HFSS simulation, thickness of patch has been optimized. Finally, the measured data are got basically consistent with simulation result. The result shows that the single patch polarization twist waveguide has lower VSWR and insertion loss and may meet the requirement of application.
