Industry driven research will allow the PhD students develop a comprehensive set of skills relevant for a long-term employability in the sector of satellite communication area. It is highly likely that the candidate will be employed directly at Satcube AB or other companies in relevant sector after the PhD studies.
Project description
The PhD project will be a collaboration among Chalmers, Uppsala University and the industrial partner Satcube AB. The PhD studies will be partially funded by Satcube AB, and hence the research will be carried out in close collaboration with Satcube's R&D staff. The candidate will have the opportunity to spend approximately half of her/his time at Chalmers' and Sactube's facilities respectively, in order to ensure that the candidate gains adequate insights into the application-specific antenna requirements.
Background of the project:
The 3rd Generation Partnership Project initiated new activities in March 2017 to study the role of the satellites in the 5G wireless network. It has been concluded that SATCOM can significantly enhance the 5G network reliability by ensuring service continuity, in cases where it cannot be offered networks.Thus, actors such as SpaceX, OneWeb, Telesat and Amazon are planning to launch 100000 LEO satellites in the next decade to provide global broadband coverage.
The cost of satellite user terminals is excessive and limits the large-scale deployment of commercial satellite-based high-throughput networks. One of the major cost driving components in satellite user terminal is the high gain circular polarized antenna which must be pointed accurately towards the satellites. This project will involve design/fabrication and measurement of the innovative low-cost, high efficiency and wideband circular polarized planar array which will be one of the key building blocks in the future satellite terminals providing increased data connectivity all over the world.

Electromagnetic design of highly efficient dual circular polarized, dual band, low-profile active antenna array for the 20-30GHz frequency band. The antenna should be phase controlled in one dimension, to enable electronic steering of the beam in one plane to track satellites in orbit.
• Design and selection of a suitable array topology which will allow simple feeding geometry with minimum losses. Also design of the suitable array which allows easy signal routing and feeding from the active beam former chips for dual polarized active array.
• Analysis of the integration of active beam former components. Each antenna sub-array needs to be fed with an independent phase and amplitude from a commodity beam former IC channel.
• Building a demonstrator of the proposed antenna array solution and evaluation of the performance of the array.
• Develop own scientific concepts and communicate the results of the research verbally and in writing. The position also includes teaching on undergraduate level and MSc. level corresponding to 10-15% of working hours.
Qualifications
Applicants should have, or expect to receive, a Master of Science degree or equivalent in a relevant electrical engineering or applied physics discipline. Besides good subject knowledge, emphasis will be on creative thinking, motivation, ability to cooperate, initiative to work independently and personal suitability. Previous experience in the area of Electromagnetic fields and Antenna theory as well as proficiency in using Fullwave solvers such as HFSS and CST is considered to be an advantage. The position requires sound verbal and written communication skills in English.
Contract terms
Full-time temporary employment. The position is limited to a maximum of five years.
