This paper presents the analysis and design of an open stub-based two-port discontinuity in a coplanar waveguide.The discontinuity has a pomyslnaszycie.com good bandpass response and the required design characteristics were achieved by using the method of moments (MOM) and the finite integration technique (FIT).The analysis is found to be computationally efficient which makes the discontinuity suitable for use in complex structure applications.The analysis of the discontinuity is also formulated using the quasi-static finite-difference technique.

The proposed discontinuity structure finds applications in RFICs and MMICs.Finally, the application of the discontinuity is supported by the simulated design of a broadband bandpass filter on an MMIC with a relative bandwidth of 96%.The filter is found to have a miniature size and a fairly good animed blue lotion topical spray stop band rejection.
