Abstract: In this paper an RF microelectromechanical (MEMS) tunable bandpass to bandstop transformation filter designed for 3-4.2 GHz with low insertion and return loss and the effect of substrate thickness was analyzed. The bandpass to bandstop transformation is achieved by adjusting the coupling parameters of microstrip resonator. The microstrip resonator is designed by coupling more than one microstrip lines resulting in the independent tuning of centre frequency and the bandwidth. The simulative analysis of the effect of different microstrip configurations in microstrip bandpass to bandstop tunable filter is performed using COMSOL Multiphysics software.
