Computer Aided Design of Parallel Coupled Line Microstrip Bandpass Filters

A new approach to the computer aided design of parallel o parallel coupled line microstrip bandpass filter is introduce. The solution is based on the analysis and numerical optimization of microstrip characteristicss.A complete set of design equations for parallel coupled line microstrip bandpasss filter is presented. With the help of this method S and X band bandpass filters can be designed. Experimental results show chose agreement with the predicted results and meet well the project requirement.
