Research Areas
Research Interests
Research interests focus on the design, and analysis of antenna systems. These include microstrip antennas employing both conventional and non-conventional substrates. My work also covers MIMO antenna systems for high-data-rate communications, as well as body-worn, wearable, and conformal antennas for healthcare and IoT applications. I actively explore defected ground structures (DGS) and electromagnetic bandgap (EBG) etc. techniques for performance improvement and mutual coupling reduction. In addition, I investigate dielectric resonator antennas, different materials, and innovative geometries to achieve compact and high-performance antenna solutions for emerging wireless systems. Currently, started working on simulation based TFET and application of AI/ML in antenna.
