Novel Low Pass Filters Using a Defected Microstrip Structure

In this article, the stop-band characteristics of a novel defected microstrip structure (DMS) are studied and its application to a low pass filter is proposed. The equivalent circuit model of the unit defected microstrip structure is used to explain th...
A novel defected microstrip structure (DMS), which behaves in a way similar to the known defected ground structure (DGS) unit cell, 1–10 is studied in this article. The unit DMS 3,4 is made by etching slots in the microstrip line, which then exhibits the property of rejecting microwaves at...
