A New Microwave Bandstop Filter Using Defected Microstrip Structure (DMS)

摘要

This paper presents a new bandstop filter by creation of some slots on the strip. These slots perform a serious LC resonance property in certain frequency and suppress the spurious signals. In the high frequencies applications, the board area is seriously limited, so using this filter; the circuit area is minimized. The proposed filter is very suitable for high density MMIC circuits.
