History and Growth of the Department:
The Department of Electronics Engineering was established in the year 1972 and has steadily grown from offering short-term training courses to M.Tech, MS (By Research), and Ph.D. programmes. The Department currently offers M.Tech., in Electronics and Communication Engineering with an intake of 75 students
distributed in the specializations of

  • Signal Processing and Communication,
  • Radar and Communication,
  • Defence Electronics Systems,
  • VLSI and Embedded System (since 2017).

Being in Defence University, the Department offers M. Tech, MS(By Research), and Ph. D. programs in electronics and communication engineering and engaged in conducting various short-term courses to DRDO and Defence Officers. This programme is open for DRDO Scientists/Officers and Officers from Tri-services, Defence public sector undertaking, Industry personal, and civilian students. Currently, the Department is well equipped with different advanced lab facilities such as Communication lab, Antenna Lab, SOC, and Embedded System Lab. The Department is working on many sponsored research projects, and the researchers have developed a range of products, including SAR radar, Photonics Radar, etc. Moreover, the Department participates extensively in R&D activities in collaboration with Defence Labs and Establishments of India. The curriculum is designed for students to collaborate with DRDO labs, DPS’U, Reputed institutes, and Industries for the dissertation with the defined project objectives. This encourages and motivates the students to publish papers in peer-reviewed journals, national and international conferences, filing patents, etc. Such collaborations have improved placements and registering for Ph.D. in IITs, IISc, and international Universities.

Vision of the Department: To be a center of excellence of international repute to provide high-quality education, research, and training in the area of Radar and Communications, Signal Processing and Communications, Defence Electronics Systems, VLSI, and Embedded Systems to promote innovation and entrepreneurship skills amongst the students to strengthen national security and self-reliance.

Mission: To establish state-of-art research facilities to train the personnel as per the Defence needs, especially in Electronics and Communication fields, and produce qualified quality human resources for the Defence requirements.
