This seminar focuses on a novel and versatile technique which is being explored over the last two decades ensuring enormous possibility of advancement in planar antenna and array technology. It, indeed, is Defected Ground Structure (DGS) which originated from the electromagnetic band gap concept and was confined to the printed circuits at its early phase. In 2005, DGS was first explored for antennas, with a special application to addressing the cross-polarization issues. It grew rapidly as a new and versatile technique. This presentation addresses its fundamental principles, the physical insights, and chronological advancement leading to the state-of-the-art achievement in terms of uniform suppression of cross-polar fields.
