Highly innovative and industry driven research will allow the working researcher to develop a comprehensive set of theoretical and practical skills relevant for innovation and long-term employability in the rapidly growing sector of wireless communication area.
Information about the research
There is an emergent need for a higher data rate for upcoming wireless applications. Given the data rate, capacity, and quality of service (QoS) requirements, this can only be possible if the vast unlicensed bandwidth available at mmWave frequencies can be utilized and all the technical hurdles at mmWave frequencies (above 30 GHz) are solved cost-effectively. Regarding bandwidth worldwide and flexible transmission rules, 60GHz is a boon from a system perspective. However, RF designers have faced enormous challenges in simulation, design, integration, physical realization, packaging, and testing of the complete systems. The technical challenge is more complex than today's 2.4GHz or 5GHz Wi-Fi systems.
The gap waveguide technology can potentially be used as a low-loss mmWave technology and a potential candidate for THz. The main advantages of the gap waveguide structure are: Gap waveguide is a waveguide where EM wave can be guided and controlled even in an oversized parallel-plate structure. The waveguide can be realized without any metal contact requirement between the conducting surfaces' layers. Thus, allowing cheap manufacturing of low-loss guiding structures and related components at mmWave frequency bands compared to the conventional waveguide components. The relaxed mechanical requirements pave the way for development of low loss and high efficiency waveguide antenna systems which are very relevant for next generation wireless systems.

Electromagnetic design of high efficiency dual polarized gap waveguide antenna array for fixed beam application scenario around mmWave frequency band.
• Electromagnetic design of highly efficient dual circular polarized gap waveguide antenna array suitable for beam scanning applications around mmWave frequency band.
• Design and selection of a suitable array topology which will allow simple feeding geometry for passive antenna case. Also design of the suitable array which allows easy signal routing and feeding from the active beam former chips for dual polarized active array.
• Responsibilities as researcher also involves supervision of doctoral students in their research topics. Also, to propose novel scientific concepts and communicate the results of the research verbally and in writing. The position generally also includes teaching on Chalmers' undergraduate level and MSc. level corresponding to 10% of working hours.
Qualifications
Applicants should have, or expect to receive, a PhD degree or equivalent in a relevant electrical engineering or applied physics discipline. In addition to the formal qualifications, selection is also based on the performance of the candidates in other works (e.g. thesis and advanced level courses, their research experience), as well as through interviews and assignments. Besides good subject knowledge, emphasis will be on creative thinking, motivation, ability to cooperate, initiative to work independently and personal suitability for research training and supervision.
Contract terms
The position is a full time temporary employment, limited to a maximum of 360 days.
