摘　　要：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一槽线转接器与非对称共面波导一槽线转接器在3～8GHz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．An asymmetric coplanar waveguide （ACPW） transi- tion was designed to further improve the connecting flexibility of coplanar waveguide （CPW） slotline. The S-parameters of transition of symmetric CPW-slotline （SCPW-slotline） and ACPW- slotline between 3--8 GHz were calculated by using finite-difference time-domain （FDTD） method based on Mur-PML absorb- ing boundary condition. Results show that the calculated value matches well with the measured value, and transition of ACPW- slotline is superior to that of SCPW-slotline in respect of flexibility of design and impendence match.
