Abstract:

 

In this paper a new method has been presented to design   spatial band-pass filters consisting of dielectric backed conducting strips.   This approach uses an equivalent circuit model in which determined inductive   elements are spaced at intervals about half wavelength. To realize the   proposed method, the inductive elements have been replaced by dielectric   backed conducting strips located at intervals about half wavelength. Half   wavelength transmission line sections act as resonators. In this manner the   wideness and spacing of strips in each dielectric backed conducting strip,   as well as the distance between them, is determined by fitting the   characteristic (transfer function) of the proposed filter to that of a   desired one obtained from an equivalent circuit model. To take the effect of   higher order modes (evanescent mode), a coupled set of magnetic field   integral equations is derived and formulated. Finally a set of linear matrix   equations are solved using method of moments (MoM) and entire basis   functions have been used resulting in rapid convergence. The usefulness of   the proposed structure and its performance are verified by designing and   simulating an equal ripple Chebyshev-type and a Butterworth-type spatial   band-pass filter.
