✦ Synopsis

The paper presents the internal details of a developed full-wave algorithm for the computer-aided design of evanescent-mode bandpass filters formed by single-or doubleshort ridged waveguide sections. New filter configurations with an enlarged cross section of filter housing and nonconventional notch-strip-notch elements providing improved stopband performance are given special considerations. Additional input-output transformers built on rectangular waveguide sections are used in designing broadband filters. Characteristics of one of the designed filters are verified by measured data.

## Abstract In this article, resonant characteristics of novel microstrip resonators based on the Sierpinski carpet fractal geometries are proposed in detail. With increasing the iteration order of the Sierpinski‐based fractal resonators, the resonant frequency is decreased but the unloaded quality
