An Example of Suppression of Spurious Stop-Bands of EBG Band-Stop FilterKeywords: Band-stop filter , Suppression of spurious stop-bands , Microstrip Abstract: Based on the well known theory of infinite periodic structures, analytical theory of EBG (electromagnetic band gap) cells suppressing 6 higher (spurious) stop-bands is developed. Using such cells in a cascade the straight-forward procedure for design of the corresponding EBG band-stop filter is proposed, with possibility to control the width and the depth of the stop-band. The analytical theory is confirmed by the EM simulation of the filter realized in the microstrip technology.
