RF/ Microwave Engineering - Research area is RF/Microwave Engineering, presently working in design of microwave passive devices like fractal antennas, power dividers, couplers and filters for wireless applications. My research work mainly focus on reducing the size of the various RF passive devices using slow wave structures, sub wavelength resonators, dual transmission line etc., without any compromise on their performance. I am very much interested in design and development of RF devices/components for high-frequency applications (X-band, ka-band etc.) and also to solve any real time and industry oriented RF related design issues.
