Dr. Ravi Prakash Verma

Biography

Mr. Ravi Prakash Verma is currently serving as an Assistant Professor in the Department of Electronics and Communication Engineering, Jaypee Institute of Information Technology (JIIT), Noida, Uttar Pradesh, India. He received his B.Tech. degree in Electronics and Communication Engineering and M.Tech. in Microwave Engineering from Uttar Pradesh Technical University, Lucknow, in the years 2009 and 2015, respectively. Mr. Ravi is also pursuing his Ph.D. from JIIT, Noida. With over 13.5 years of academic and research experience, Mr. Ravi has been actively engaged in academic instruction, research, and course coordination. His expertise lies in the RF and microwave field, with research interests in the area of design and fabrication of microstrip filters, antennas, and filtering antennas. Mr. Ravi has taken several key roles at JIIT, serving as an instructor in the Pre-Engineering Program and acting as a course coordinator for both the theory and lab courses. He is also engaged in coordinating and establishing a new IEEE Antenna and Propagation Society (AP-S) Student Branch Chapter (SBC) at JIIT Noida.

Research Highlights

Mr. Ravi’s research is centred on RF and microwave engineering, with a particular emphasis on microstrip and substrate integrated waveguide (SIW) technologies for modern wireless systems, including 5G and beyond. His work encompasses the design, analysis, and fabrication of key components such as bandpass filters, antennas, and filtering antennas. A significant contribution of his research is a comprehensive study of UWB filter topologies, addressing design trade-offs, size optimization strategies, and emerging trends toward integrated filtering solutions. He has proposed innovative designs, including a compact bandpass filter with tunable bandwidth and notch frequencies, which enhance frequency selectivity and interference mitigation. To provide deeper insights into component behavior and its effect on signal integrity, a study is also presented to design an electrical equivalent circuit model for distributed bandpass filters and filtering antennas. Furthermore, an integrated filtering antennas with tunable radiation null, enabling customized interference suppression for application-specific requirements. Specifically, a compact circular coaxial-fed radiator filtering antenna featuring configurable radiation nulls, reflects an improved out-of-band suppression and enhanced interference rejection for n77/n78 5G frequency bands.
