PhD Studentship: RF and Microwave Engineering - Multiport Devices for Emerging 5G6G and Satellite Communication Systems

A PhD studentship in RF and Microwave Engineering is available within the Birmingham Emerging Device Technology (EDT) Research Lab, one of the leading interdisciplinary research groups within the School of Engineering’s Department of Electronic, Electrical and Systems Engineering. A primary focus of research within the department is to develop novel technologies [1,2] for emerging 5G/6G and satellite communication systems. The aim of the PhD is to investigate, design and fabricate multi-port glass-based components (e.g. isolators, circulators, and loads) for >60 GHz duplexer applications.

Background and aims: As we move towards the future of large communication networks and remote sensing, applications such as 6G communications will require higher data rates, wider bandwidth, and stronger channel fidelity. Several of the targeted 6G frequency bands are even being considered for extremely high frequency bands such as the W-band (75–110 GHz) and the D-band (110–170 GHz).

In order to achieve these goals, novel solutions for RF components and their production are required to achieve repeatable and high-accuracy fabrication as well as enable low loss properties. Glass-based technology and packaging is being considered as new and viable candidate that enables excellent material properties such as high-accuracy, very low surface roughness, light weight, and chemical resistance. This PhD project will aim to make foundational work in glass-based RF components and packaging techniques, with specific aims including:

- Investigate design methods that are suitable multi-port RF components using 3D EM modelling tools (CST or HFSS)
- Fabricate and test for optimal electromagnetic performance, such as bandwidth, return loss, insertion loss and power-handling.
- Develop and characterize new bonding/alignment techniques, fabrication processes and methodology
- Contribute to scientific talks, conferences, meetings, discussions and other group activities.

The project will suit someone wishing to do a PhD in the development of new and practical applications of RF/microwave systems. It will provide an opportunity to develop a wide range of skills and experience in microwave, material processing, high-precision fabrication and RF measurements. The PhD will be hosted by the School of Engineering. However, the student will work across colleges, occupy labs with the group, and be encouraged to collaborate with our wider network.

To apply: Please send a CV and covering letter to Dr Chad Bartlett at c.bartlett@bham.ac.uk. Your letter should explain your relevant experience and why you are a suitable candidate for the project. Informal enquiries are welcome.

Funding notes:
