Current transmitters are limited in terms of their bandwidth, energy efficiency and linearity. In this research project you will work on the intersectional area of antenna design, circuit design and signal processing to investigate novel nonlinear multi-antenna transmitters that overcome these limitations. By utilizing antenna mutual coupling for effective amplitude modulation – a shift from the traditional view that considers it detrimental – you will overcome existing limitations in frequency, efficiency, power, and linearity, thereby fostering sustainable digital transformation.About us The position is hosted by https://www.chalmers.se/en/departments/mc2/research/microwave-electronics/ at https://www.chalmers.se/en/departments/mc2/ where the you will have access to several commercial state-of-the art MMIC foundry processes and world-class measurement infrastructure allowing for a successful completion of this research project. At the Microwave Electronics laboratory currently 5 students pursue their Ph.D. in a similar area, which plenty of opportunity to collaborate and learn from and with peers. About the research project You will work in a complementary team to investigate a new transmitter topology. Your responsibility will be to design microwave components such as power amplifiers and antenna arrays but also derive the theory how to feed the individual amplifiers for the most energy efficient transmission in a certain direction. The goal is to develop a new scalable transmitter architecture that embraces mutual antenna coupling as a means of load modulation - allowing neighboring elements to efficiently create modulated signals similar to classical Chireix outphasing, but using the antenna apertur…DoktorandDoktorander
