Guha and his research group have contributed towards the development of science and engineering for both microstrip antennas and dielectric resonator antennas (DRAs).

Guha introduced the concept of defected ground structure (DGS) integration technique to microstrip antennas{{Cite journal|last1=Guha|first1=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|s2cid=27170050 }} 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{{Cite journal|last1=Guha|first1=D.|last2=Biswas|first2=M.|last3=Antar|first3=Y.

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.{{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 and Wireless Propagation Letters | volume=19 | number=1 | pages=99–103 | date=January 2020| doi=10.1109/LAWP.2019.2954215 | bibcode=2020IAWPL..19...99D | s2cid=209907041 }}{{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 Transactions on Antennas and Propagation| volume=68 | issue=6 | pages=4950–4954 | date=June 2020| doi=10.1109/TAP.2019.2955212 | bibcode=2020ITAP...68.4950P | s2cid=213826749 }}

His original contributions to dielectric resonator antennas encompass (i) the introduction of a new and truly useful radiating mode in cylindrical DRAs{{cite journal | doi=10.1109/TAP.2011.2167922 | title=Higher Order Mode Excitation for High-Gain Broadside Radiation from Cylindrical Dielectric Resonator Antennas | date=2012 | last1=Guha | first1=D. | last2=Banerjee | first2=A. | last3=Kumar | first3=C. | journal=IEEE Transactions on Antennas and Propagation | volume=60 | issue=1 | pages=71–77 | bibcode=2012ITAP...60...71G }} and (ii) concept of multi-mode engineering - a more theory-based methodology using composite and hybrid structures,{{cite journal | first1=Debatosh | last1=Guha | first2=Y. | last2=Antar | title=Four-element cylindrical dielectric resonator antenna for wideband monopole-like radiation | journal= IEEE Transactions on Antennas and Propagation| volume=54 | issue=9 | pages=2657–2662 | date=September 2006| doi=10.1109/TAP.2006.880766 | bibcode=2006ITAP...54.2657G | s2cid=31923813 }}{{cite journal | doi=10.1109/TAP.2006.886547 | title=New Half-Hemispherical Dielectric Resonator Antenna for Broadband Monopole-Type Radiation | date=2006 | last1=Guha | first1=Debatosh | last2=Antar | first2=Yahia M.
