Analysis and modelling of novel band stop and band pass millimeter wave filters using defected microstrip structure (DMS)

This paper presents novel millimeter wave filter structures 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 high frequencies and high density applications, the board area is seriously limited, so using these filters; the circuit area is minimized. The proposed filters are compact and very suitable for high density MMIC circuits.
