Abstract

A MEMS based tunable bandstop filter using electromagnetic bandgap (EBG) structure is proposed in this paper. A tunable band-stop filter (BSF) has been designed with flat response at a selected frequency by incorporating microelectromechanical systems (MEMS) bridges. An equivalent circuit model for the tunable bandstop filter is derived and its parameters are extracted by using commercial software. High resistivity silicon substrate and MEMS surface micromachining process are employed. The measurement results for the tunable band stop filter reveals a tuning range from 19 GHz to 17.3 GHz. Additionally, low-pass-band insertion loss is found to be 1.3- 2.4 dB.
