Abstract: A UWB bandpass filter has been presented in this study. The filter has been designed on a silicon substrate with Perfect Electric Conductor (PEC) microstrip parallel-coupled stub resonators. The filter comprises of Wave port, Infinite Ground Plane and 1 GHz bandwidth with centre frequency, f0 being 1.5 GHz ranges from 0.6-2.4 GHz. The filter has been designed and verified by HFSS simulation.
