A Novel Bandpass Defected Microstrip Structure (DMS) Filter for Planar Circuits

摘要

A new defected microstrip structure (DMS) unit lattice is proposed in order to perform a bandpass filter (BPF). The proposed DMS provides the good cutoff 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%.
