The IEEE AP/ED/MTT North Italy is pleased to announce the IEEE Distinguished Antennas and Propagation Lecture entitled "Uniformly Low Cross-Polar Design of Planar Antenna and Arrays: Advances in Engineering and New Insights" by Prof. Debatosh GUHA (University of Calcutta, India) which will be held onsite (Room 1H, DICAM, Via Mesiano 77, 38123 Trento) and online on Friday July 12th, 11:00 AM.

Contact point: Prof. Paolo ROCCA (paolo.rocca@unitn.it)

Abstract

This talk will address 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 will address 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.

Debatosh Guha is a Professor in Radio Physics and Electronics, University of Calcutta and Dean for the Faculty of Engineering and Technology. He is a Fellow of IEEE, Abdul Kalam Technology Innovation National Fellow, and also a fellow of all four National Academies for Sciences and Engineering in India. He has served IEEE Transactions on Antennas and Propagation and IEEE Antennas and Wireless Propagation Letters as an Associate Editor, and IEEE Antennas and Propagation Magazine as a Section Editor. He has been serving IEEE AP Society and URSI Commission-B in various capacities. At present, he is the Chair of IEEE AP-S MGA Committee and also a Distinguished Lecturer of IEEE AP Society. His research interests include low-profile antenna techniques. A couple of books on antenna engineering published by IEEE Press and Wiley are to his credit.
