The Department of Electronics and Nanoengineering conducts research and arranges related courses in the field of electromagnetics, micro and nanotechnology, radio engineering, and space technology featuring an international team of over 150 Researchers and Research Assistants. The Department is part of the Aalto University School of Electrical Engineering (Aalto ELEC) with world-class research facilities and instruments.
The Antennas and Propagation group of Aalto University School of Electrical Engineering is looking for a
Part-time Research Assistant for Antenna Radome Design in 5G Base Stations
to join the research work.
The fifth-generation (5G) cellular wireless has started its roll out in many countries. Successful deployment of 5G radios require a robust infrastructure so that cellular wireless coverage is ensured with commodity mobile devices. Wireless infrastructure incorporates various practical components. For 5G, much higher frequencies are used than for traditional cellular systems, such that wavelengths and hence antennas become physically smaller while electrically larger for beamsteering. This means that 5G base stations can be small enough for convenient deployment. The goal of this part-time research assistant position is the design of a planar antenna radome for a millimeter-wave antenna array intended for 5G base stations. Generally, a radome protects an antenna from environmental disturbances such as rain, snow and wind. At the same time, the radome should be designed such that it does not interfere too much with the intended electromagnetic radiation from the antenna array.
The part-time research assistant addresses improvement of existing radome design for further refinement and design verification through fabrication of the radome. The assistant is expected to accomplish the following tasks:
1. Understanding the current designs of radomes, which are available in CST Microwave Studio;
2. Performing systematic parametric studies to further optimize radome dimension and performance;
3. Designing a reference radome for benchmarking of the radomes; and finally,
4. [Optional] Fabrication of the designed radome(s) and measuring its performance in a laboratory.
The study will involve interaction with Finnish industry partners committed to the development of 5G infrastructure.
Associate Professor Katsuyuki Haneda leads the Antennas and propagation research group, which has been involved into several EU FP7 and Horizon 2020 projects about 5G-and-beyond physical layer studies and hence is known internationally to scientific and industrial research communities. Applications of the developed knowledge and experimental facilities about 5G-and-beyond cellular to industries are one of the key research missions of the group.
Experience of numerical simulations of passive radio frequency components and fields using, e.g., CST Microwave Studio and MATLAB. It is advantageous if the applicant has the following knowledge and skills:
• Experience of radio frequency instrumentation and measurements, e.g., antennas and field tests
• Basic understanding of 5G cellular radio systems, e.g., the need of phased antenna array beamforming instead of fully digital beamforming.
Only students studying for a master’s degree can apply for this position, applicants who already have a master’s degree are not eligible.
Salary and contract
This part-time research assistant position will be filled up to four (4) months with maximum 50% of commitment; the percentage may be also smaller, depending on the number of courses one is attending. The salary follows the standard salary level of research assistants in the School of Electrical Engineering, based on the acquired study credits. We prefer that the work starts as soon as possible.
