Art and Challenges in Low Cross-Polar Antenna Design

This talk will address a novel and versatile technique which has been 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 antenna design, with a special application to addressing the cross-polarization issues. It grew rapidly as a new and versatile technique. This presentation will address its fundamental principles, the physical insights, and chronological advancement leading to the state-of-the-art achievements.
