Additive manufacturing (AM), or 3D-printing, is bringing a revolution to most engineering areas. It is not just about changing fabrication processes and materials, but more importantly, enabling powerful new concepts and designs not feasible or affordable with traditional manufacturing. In parallel, personal communications present a meteoric evolution that impregnates each one’s life and habits. This growth will continue embodying concepts like the Internet of Things (IoT), satellite communications and next generation mobile communications (beyond 5G). It will transparently link much more users, machines, sensors and virtual nodes through land and satellite infrastructures. It requires effective low-cost solutions for mass-market. AM will play a role, and antennas are a key player in wireless systems. The project focuses on the development of new antenna concepts using AM for 5G, Satellite communications, IoT and associated applications, such as body-area networks.
General Requirements
1. Doctorate degree in Electrical and Computer Engineering

Requirements:
Applicants should have, or expect to receive, a Master of Science degree or equivalent in a relevant electrical engineering or applied physics discipline and should not have more than four years of research experience. In addition to the formal Research Fellow qualifications, selection is also based on the performance of the candidates in other works (e.g. thesis and advanced level courses), 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. Previous experience in the area of antennas, electronics and signal processing as well as proficiency in using scientific and engineering software packages such as Matlab, ADS, CST, HFSS etc. are advantageous. For the PhD positions the EU ‘Mobility rules’ apply. This means that candidate students cannot have resided for more than 12 months during the period of 3 years immediately before the start of the PhD, in the prospective first host country (Example: a candidate who has stayed in The Netherlands for more than 12 months in the last 3 years cannot be hired for the position where the first placement is at the university in The Netherlands).
Applications for the position must be submitted via the application systems of the host organisations. The links are provided below.

Satellite front-end system for non-terrestrial 6G
The aim of this PhD project is to develop innovative phased arrays architectures for 6G satellites, that must radiate multiple beams in Rx/Tx with high gain over a wide angular sector in reconfigurable frequency bands, while complying with severe power consumption and accommodation constraints. New concepts based on deployable phased arrays must be explored with integrated radiating elements with wide angle scanning capability over multiple bands, with hybrid beamforming (RF, digital, photonic), distributed filtering and amplification, resulting in a low profile, integrated and deployable antenna. The expected outcome of this project is an assessment of several antenna architectures based on different approaches. The key building blocks must be designed and prototyped. Moreover, specifications of key building blocks for other PhD projects shall be derived.

Integrated Photonic-RF front-end
: The objective of this PhD project is to explore and develop integrated photonic RF front-end solutions based on the latest integrated photonics platforms (incl. InP, Silicon, Ln/Si, IMOS) to squeeze the SWAP of these interfaces while maintaining the required level of RF performance. The PhD student is expected to study suitable modulator technologies for both phase and intensity modulation (with MZM or electro-absorption modulators) and to design an integrated photonic front-end for transmission of Ka-band RF signals with and without frequency conversion. The compatibility and potential for co-integration with optical beamforming shall be analyzed. The expected outcome includes a SWAP analysis for integrated photonic-RF front-ends considering the latest integrated photonics platforms and different modulator technologies as well as the design and prototype of a novel power-efficient integrated photonic-RF front-end.
