Accurate Synthesis and Design of Wideband and Inhomogeneous Inductive Waveguide Filters

The Simulation, Design and Implementation of Bandpass Filters in Rectangular Waveguides

“…where S 11 and S 22 are equal to -1 in the good conductor area and S 12 and S 21 are equal to +1 for the free space. To transform the wave from the spatial domain to the spectrum domain, we use the Fast Fourier Transform (FFT)…”

“…Many accurate techniques have also been proposed but have complex algorithms [9][10][11][12]. The Ref.…”

“…However, this method can also be expanded to analyze TM modes and for designing multi-mode planar waveguides. Also, an accurate CAD tool based on the merging the prototype synthesis and the structure extraction has been presented in [11] for the particular case of inline inductive waveguide filters.…”

Distributed Models for Filter Synthesis

“…It is well known that such filter responses and configurations cannot be directly recovered from classic synthesis methods based on equivalent circuits composed of constant impedance inverters and equal transmission line resonators [4], [5]. The performance of traditional [11], [19] and recent [21], [35] synthesis techniques including frequency-dependent elements are compared through the design of a moderate bandwidth, a wideband and an inhomogeneous H-plane filter. The synthesis technique based on a flexible prototype able to represent the real structure behavior [36] yields the best results.…”

“…Los resultados de la primera aplicación de la nueva metodología, recientemente publicados en [153], [154], mostrarán las grandes ventajas que ésta proporciona sobre las técnicas de diseño tradicionales.…”
