A Novel Bandpass Defected Microstrip Structure (DMS) Filter for

A new defected microstrip structure (DMS) unit lattice is proposed in order to perform a bandpass fllter (BPF). The proposed DMS provides the good cutofi and passband characteristics. Also in this paper we extract the model of BPF. In order to show the improved the parameters, several circuits were designed and simulated. The BPF has a bandwidth more than 39%.
