Research Statements

  • A new class of metal-dielectric hybrid subarray has been introduced with the aim of achieving maximum advantage out of minimum feed and element requirements [IEEE TAP, 69 (7), 3778 - 3787, 2021].
  • A novel concept of ‘open cavity resonant antenna’ along with an AI-based theory has been introduced as an improved variant of the traditional Fabry-Perot cavity [IEEE AWPL, 20 (5) 678-682, 2021]. This design is under progress at ISRO for realizing a unique feed in satellite-borne reflectors.
  • The first time solution to the long-standing issue of high cross-polar fields across the skewed radiation planes of any microstrip antenna [IEEE TAP, 68 (6), 4950 - 4954, 2020], [IEEE AWPL, 19 (1), 99-103, 2020]. This indeed solves the major shortcoming in SAR antennas and is already in process for the practical applications.
  • Reported the glue-free mount for Dielectric Resonator Antennas [IEEE AWPL, 16, 2440-2443, 2017] for the first time. This is going to solve the major weakness of using this antenna on highly vibrating platforms like air-borne and space-borne systems.
  • Introduced a new radiating mode (HEM12) in cylindrical shaped Dielectric Resonator Antenna (DRA) and successfully resolved the challenges of its excitation by innovating a series of novel feeds [IEEE TAP, 60 (1), 71-77, 2012]. This overall approach enables cylindrical DRA qualified for on-chip implementation.
  • Conceived and introduced Defected Ground Structure (DGS) integration techniques to planar antennas for mitigating cross-polarized radiations and mutual coupling in array elements [IEEE AWPL, 4, 455-458, 2005]. This has been eventually established it as an attractive and industry-qualified technique.
