==Research and Published works==

Guha and his research group have contributed towards the development of science and engineering for both [[microstrip antenna]] and [[Dielectric Resonator Antenna]] (DRA).
Guha introduced the concept of [[Defected Ground Structure]] (DGS) integration technique to [[microstrip antenna]]<ref>{{Cite journal|last=Guha|first=D.|last2=Biswas|first2=M.|last3=Antar|first3=Y. M. M.|date=2005-01-01|title=Microstrip patch antenna with defected ground structure for cross polarization suppression|journal=IEEE Antennas and Wireless Propagation Letters|volume=4|issue=1|pages=455–458|doi=10.1109/LAWP.2005.860211|issn=1536-1225|bibcode=2005IAWPL...4..455G}}</ref> and developed the theoretical understanding followed by experiments. His group explained the mechanism of weakening the cross-pol generating modes and mitigating two major issues in microstrip elements and arrays: (i) high cross-polarized radiations<ref>{{Cite journal|last=Guha|first=D.|last2=Biswas|first2=M.|last3=Antar|first3=Y. M. M.|date=2005-01-01|title=Microstrip patch antenna with defected ground structure for cross polarization suppression|journal=IEEE Antennas and Wireless Propagation Letters|volume=4|issue=1|pages=455–458|doi=10.1109/LAWP.2005.860211|issn=1536-1225|bibcode=2005IAWPL...4..455G}}</ref> and (ii) mutual coupling among array elements<ref>{{Cite journal|last=Guha|first=D.|last2=Biswas|first2=S.|last3=Biswas|first3=M.|last4=Siddiqui|first4=J. Y.|last5=Antar|first5=Y. M.

Hou, et al., "Elimination of scan blindness with compact defected ground structures in microstrip phased array," IET Microwaves, Antennas and Propagation, vol. 3, no. 2, pp. 269 – 275, March 2009</ref>

A long challenging issue of high cross-polarized radiations occurring across the diagonal planes of a microstrip patch has been resolved by his group in 2020. The source of the problem has been theoretically identified along with some representative solutions in two different ground current conditions.<ref>{{cite journal | first1=Debi | last1=Dutta | first2=Sk | last2=Rafidul | first3=Debatosh | last3=Guha | first4=C | last4=Kumar | title=Suppression of Cross-Polarized Fields of Microstrip Patch across All Skewed and Orthogonal Radiation Planes | journal=IEEE Antennas Wireless Propag. Lett. | volume=19 | number=1 | pages=99–103 | date=January 2020}}</ref><ref>{{cite journal | first1=I. | last1=Pasha | first2=C. | last2=Kumar | first3=Debatosh | last3=Guha | title=Mitigating High Cross-Polarized Radiation Issues over the Diagonal Planes of Microstrip Patches | journal=IEEE Trans. Antennas Propag. | volume=68 | issue=6 | pages=4950–4954 | date=June 2020}}</ref>

His original contributions to [[Dielectric Resonator Antenna]]s (DRAs) encompass (i) introduction of a new and a truly useful radiating mode in cylindrical DRAs<ref>Debatosh Guha, Archita Banerjee, C. Kumar, Y. Antar, "Higher Order Mode for High Gain Broadside Radiation from Cylindrical Dielectric Resonator Antennas," IEEE Trans. Antennas Propag., vol.60, no. 1, pp. 71-77, Jan. 2012</ref> and (ii) concept of multi-mode engineering - a more theory-based methodology using composite and hybrid structures,<ref>{{cite journal | first1=Debatosh | last1=Guha | first2=Y. | last2=Antar | title=Four-element cylindrical dielectric resonator antenna for wideband monopole-like radiation | journal=IEEE Trans. Antennas Propag. | volume=54 | issue=9 | pages=2657–2662 | date=September 2006}}</ref><ref>Debatosh Guha and Y. Antar, "New half-hemispherical dielectric resonator antenna for broadband monopole-type radiation," IEEE Trans. Antennas Propag., vol.54, no. 12, pp. 3621-3628, Dec. 2006</ref><ref>Debatosh Guha, et al., "Improved design guidelines for the ultra wideband monopole-dielectric resonator antenna," IEEE Antennas Wireless Propag. Lett., vol.5, pp. 373-376, Dec. 2006</ref> which changed the traditional concept of wideband or ultra-wideband DRA designs. To establish the viability of the new mode, he has developed new feeding techniques<ref>Debatosh Guha, et al., "New Technique to Excite Higher Order Radiating Mode in a Cylindrical Dielectric Resonator Antenna," IEEE Antennas Wireless Propag. Lett., vol.13, pp. 15-18, Dec. 2014</ref><ref>Debatosh Guha, Poulomi Gupta, and C. Kumar, "Dualband Cylindrical Dielectric Resonator Antenna Employing HEM11δ and HEM12δ Modes Excited by New Composite Aperture," IEEE Trans.
