The presented process includes the estimation of filter parameters using analytical formulas, finding the corresponding low-pass prototype structure impedance and frequency scaling is performed to achieve a band pass filter. The pass-band filter is then implemented using end-coupled microstrip lines, the lengths of these lines and the gaps between them are obtained by using analytical formulas. The structure of this filter is simulated using Ansoft designer SV2.2 simulator. Good agreement between theoretical and simulated results is observed.enArticle
