Abstract :
This paper presents a compact RF microelectromechanical system (RF MEMS) tunable filter which is based on electromagnetic bandgap (EBG) structures. The frequency response for the proposed bandstop filter has been investigated through finite element analysis (FEA). By studying the distributions of electric and magnetic fields, we have examined the impact of geometric parameters on filter´s centre frequency and optimized the design for Ka-band application. The numerical calculations reveals that the tunable bandstop filter achieves a tuning range from 29.2 GHz to 30.3 GHz.
