The Department of Electrical Engineering is an international workplace with around 150 employees that all contribute to important technical energy and health challenges at the Ångström Laboratory.

The position will be at the division Solid-State Electronics, at the Department of Electrical Engineering.

Project description
The EU-funded POWERFLEX project introduces an innovative solution for high-power and high-frequency conformal antennae, featuring a novel flexible GaN power amplifier, a low noise amplifier based on carbon nanotube technology, and flexible RFMEMS technologies, all seamlessly integrated through 2D monolithic integration. A distinguishing feature of POWERFLEX lies in its unconventional cooling strategy. The project aims to implement a flexible organic-based thermal platform to cool the amplifier. This innovative approach not only showcases the project's commitment to pushing technological boundaries but also enhances the overall performance and reliability of the system. The primary objective of POWERFLEX is to deliver X, Ku, K and Ka-band (flexible) antenna arrays demonstrators with active beamforming and beamsteering capabilities.

Duties

• Realize the electromagnetic design of highly efficient circular polarized low-profile active antenna array for the frequency band 20-30 GHz
• Analyzing the interconnect between the active components and the antenna sub-array
• Realize the integration of active beam former components
• Amplifier design, such as LNA and power amplifiers
• Building demonstrators of the proposed antenna array solution
• And finally, perform antenna array measurements of beamforming and beamsteering in an anechoic chamber
• Project follow-up and reporting.
• Publication of several high ranked journal papers is expected during the project duration.
• The work duties can also include teaching. No more than 20%.

Requirements

• The applicant must hold a PhD degree or a foreign degree equivalent to a PhD degree in Physics or Electrical Engineering or equivalent.
  The degree needs to be obtained by the time of the decision of employment. Those who have obtained a PhD degree three years prior to the application deadline are primarily considered for the employment. The starting point of the three-year frame period is the application deadline. Due to special circumstances, the degree may have been obtained earlier. The three-year period can be extended due to circumstances such as sick leave, parental leave, duties in labour unions, etc.
• Previous experience in the field of Electromagnetic Fields and Antenna Theory, along with proficiency in using full-wave solvers such as HFSS and CST, is considered necessary. Proven experimental work in amplifier and/or antenna measurements is also required. 
•  Very good oral and written proficiency in English.
• We will put an emphasize in your personal qualities such as good collaboration and communication skills, independence of work, and result oriented work. You should be purposeful, structured and be able to work effectively both individually and in groups.

Additional qualifications
Proficiency in Electromagnetic fields, Antenna theory, and experience with full wave solvers such as HFSS and CST is essential. Applicants with demonstrated expertise in experimental work related to antenna measurements will have a distinct advantage, along with the ability to integrate and program beam formers. Excellent academic performance, as reflected in grades, is considered a merit. Preferred candidates will have familiarity with tools like microwave network analyzers (VNAs) and software for electromagnetic simulations such as HFSS, CST, or equivalent. Additionally, a solid understanding of fundamental concepts crucial for antenna array design, implementation, and measurement is desired. Beyond technical expertise, emphasis will be placed on qualities such as creative thinking, motivation, collaboration skills, initiative for independent work, and personal suitability for research training. Candidates should be capable of working effectively both independently and as part of a team.
