This non-conducting ceramic structure with partially ope n boundary is full of mysteries in terms of its resonance behavior and fee ding mechanisms. This talk will address some unveiled mysteries of DRA mod es and possibilities of realizing novel antennas and feeds which could be broadly categorized into a contrasting pair - (1) unknown modes in known D RAs and (2) known modes in unknown DRAs. Category-1 describes a new radiat ing mode that was successfully demonstrated in a cylindrical geometry and its subsequent growth in terms of various applications. The challenge of a ddressing its boundary conditions and developments of advanced feeding mec hanisms will be discussed. Category-2 deals with a different concept of hy brid/composite geometries where our known modes can be strategically emplo yed in generating useful radiation patterns. They are primarily meant for low-profile wireless device. This ‘mode-reconfiguring technique’ will be addressed elaborately focusing on the potential scopes for the future r esearch and development. In addition\, this talk will try to address a few state-of-the-art techniques such as glue-free mount for DRA and a promisi ng metal-dielectric hybrid subarray.\n\nCo-sponsored by: Staracomm Montré al\, IEEE Young Professionals\, IEEE Montréal\n\nSpeaker(s): Prof. Debato sh Guha\, \n\n2500 chemin de polytechnique\, Polytechnique Montreal\, Mont réal\, Quebec\, Canada\, H3T1j4\, Virtual: https://events.vtools.ieee.org /m/306385 LOCATION:2500 chemin de polytechnique\, Polytechnique Montreal\, Montréal\ , Quebec\, Canada\, H3T1j4\, Virtual: https://events.vtools.ieee.org/m/306 385 ORGANIZER:mohammad.sharawi@polymtl.ca SEQUENCE:3 SUMMARY:Mysteries in Dielectric Resonator Modes and Some Techniques for Adv anced Antenna Designs(APS Montréal) URL;VALUE=URI:https://events.vtools.ieee.org/m/306385 X-ALT-DESC:Description: <br /><p>Dielectric Resonator Antenna (DRA) has cro ssed a journey of about four decades and could gradually attract a larger group of researchers across the globe.
