资料介绍

分析了非对称共面波导(ACPW)的特性,利用ACPW两侧传输功率不同的特点,重新定义了非对称性系数。将带有非对称缺陷地结构(ADGS)的ACPW(ACPW—ADGS)带阻滤波器视为两个非对称共面线(ACPS)带阻滤波器,同时给出了该带阻滤波器的等效电路模型,并利用所定义的非对称性系数简化了该带阻滤波器的导纳Y矩阵。制作并测试了ACPW.ADGS带阻滤波器,结果表明由电路参数计算得到的5参数曲线与实验测试得到的S参数曲线具有较好的一致性。

The asymmetric characteristic of asymmetric coplanar waveguide (ACPW) was analyzed, and the asymmetric factor of ACPW was redefined by using the power ratio of the two sides of ACPW. The ACPW with asymmetric defected ground structure (ACPW- ADGS) can be considered as parallel connection of two asymmetric coplanar strip line, the equivalent circuit for ACPW-ADGS bandstop filter was derived. With the asymmetric factor, the Y-matrix of the ACPW-ADGS bandstop filter is simplified. The equivalent circuit parameters for ACPW-ADGS bandstop filter are extracted, the S.parameters for the equivalent circuit are calculated. The corresponding circuit was fabricated and measured, the calculated and measured S-parameters have a good ...
