Design of a symmetrical microstrip bandpass filter for S-Band frequency range

Abstract

A new type of microstrip bandpass filter is presented with a center frequency operation at 2.5GHz which lies in the S-band frequency range. The filter is designed to be much smaller compared to the same type of parallel-coupled bandpass filter. The simulation results are excellent and the filter is suitable for integration within various microwave subsystems. © 2007 Science Publications.
