为进一步提高共面波导与槽线连接的灵活性,设计一种非对称共面波导-槽线转接器.利用基于Mur-PML混合吸收边界条件的时域有限差分法,分别计算了对称共面波导-槽线转接器与非对称共面波导-槽线转接器在3~8 GHz的S参数.结果表明:计算结果与实际测试结果吻合较好;非对称共面波导-槽线转接器在设计的灵活性与阻抗匹配方面均优于对称共面波导-槽线转接器.
In order to further improve the flexibility of coplanar waveguide and slot line connection, an asymmetric coplanar waveguide - slot line adapter is designed.Using the time-domain finite difference method based on Mur-PML mixed absorption boundary conditions, Surface waveguide - slot adapter and asymmetric coplanar waveguide - slot adapter in the 3 ~ 8 GHz S parameters.The results show that: the calculated results and the actual test results agree well; Asymmetric coplanar waveguide - slot line Adapters are superior to symmetric coplanar waveguide - slot adapters in terms of design flexibility and impedance matching.
