Sumin David Joseph

Dr Sumin David Joseph is a Researcher at the School of Electrical and Electronic Engineering, University of Sheffield. His work focuses on millimeter-wave (mmWave) systems, antenna array design, wireless power transmission, and high-frequency integrated circuits. He specializes in developing innovative solutions for 5G/6G communication systems, including reconfigurable front-ends, time-modulated arrays, and energy-efficient RFICs.

His research integrates cutting-edge fabrication techniques like aerosol jet printing for antenna prototyping and explores bondwire optimization for high-frequency applications. Key contributions include dual-band mmWave down-converters, beamforming architectures, and low-power receiver mixers.

• Education details not explicitly stated in source material.
• Focus areas: mmWave systems, antenna design, wireless energy harvesting, GaAs MMICs, and beamforming.

Recent work includes field trials of channel sounding systems and propagation modeling in rural environments. He has tested novel array configurations such as 8-element steerable transmit arrays and subsampling beamforming techniques to reduce hardware complexity. His research bridges theoretical models with practical implementations through co-simulation and lab validation.

Notable contributions to antenna array integration include bondwire compensation circuits and SIW resonators on PCB/GaAs platforms. Ongoing projects explore E-band MMIC-to-antenna interconnections and vector-modulation techniques for QPSK/8PSK/16QAM signals.
