Project

For the department “Active & Passive Antennas” we are looking for an Intern for Investigation and Simulation of Innovative Antenna Concepts Active Electronically Steerable Antennas (AESAs) at our location in Ulm (Germany).

 

Description

Within the framework of state-of-the-art broadband wide-scan arrays (BW> 4:1, +/- 60° 3D Electronic Scan), an internship position (with a B.Sc./M.Sc. Thesis extension possibility) is currently open. While traditional full-wave antenna design and optimization (i.e. CST MWS, Ansys HFSS…) is expected, connected arrays and tightly coupled dipole arrays (TCDA) profit from closed-form analytical solutions that yield improved EM understanding. Through MATLAB / Python implementations, the models can be extended by including novel structures such as Artificial Dielectric Layers (ADL), yielding accurate, fast and efficient simulations when compared to full-wave approaches (1..2 s vs +10 min per iteration). In-house tools are to be validated and consolidated through development of flexible GUI-based apps to support our engineering teams. Examples of application range from (1) connected dipole/slot unit cell and finite design, (2) ADL a design and EM characterization or even (3) custom impedance tapers for ultra-wide-band (UWB) antennas.

Among your tasks, we highlight:

·  MATLAB / Phyton scripting for analytic antenna design,

·  Electromagnetic simulation using modern SW tools (i.e., CST Microwave Studio),

·  CAD-Design of innovative antenna concepts, transmission line and connector transitions,

·  Manufacturing and measurement of designed prototypes,

·  Documentation of work and presentation of results.

Inici Flexible (upon demand, availabitly of topics and candiadte suitability)
Durada

· Up to 3 Months for an Extra-curricular Internship.

· +3 Months up to 9 Months (Mandatory Internship / Bachelor or Master Thesis)

Nombre de places

 1 or 2 per year (upon demand and supervisor/project available)

Requisits

· Pursuing a Master's Degree in Electrical / Telecom Engineering or equivalent,

· Academic background in the field of EM involving topics such as microwave engineering and antenna design,

· Programming experience in scripting tools such as MATLAB or Python,

· Basic working experience with industrial electromagnetic design tools like CST MWS or ANSYS HFSS and PCB layouting with ADS, GENESYS or similar,

· Basic knowledge of RF measurement devices (VNA, PNA) and ideally with antenna characterization in anechoic chambers,

· Innovative and self-motivated attitude (think outside-of-the-box),

· Strong interpersonal and organizational skills,

· Fluent in English (min C1). Basic knowledge of German is an asset,

· EU citizens only.

Compensació · ~1100 euro/month (35h/week) with possibility to complement stipendium with Erasmus+ or MobInt scholarships,

· Flexible working times and internship duration,

· Canteen and in-company gym discounts for students

· Ambitious work and opportunity to be involved in State-of-the-Art engineering projects,

· International and agile working environment with +25 colleagues (MSc and Phd level) in the department,

· Daily supervision by a highly motivated team willing to mentor and support the intern,

· Adaptability on university regulations and deadlines,

· Possibility of internship extension to a Bachelor or Master Thesis (Master Thesis being the preferred option).

· Possibility to contribute to engineering conferences (EuMW, EuCAP, PAST, IEEE APS Symposium) and if applied, also patent registration.

Descripció

Context

The Nokia Aalborg department is part of the Nokia Standards organization, which supports development of 3GPP Radio Access specifications.

 

Project

Store and Forward architecture in Non-Terrestrial Networks (NTN) covers the scenario where the gNB is on board of a Non Geo-Stationary Orbit (NGSO) satellite and there is no simultaneous connectivity between core network and gNB (feeder link) and gNB and UE (service link). This architecture allows a system with one or a few ground stations and a few satellites to collect data from IoT devices on Earth.

 

Description

The project has the following objectives:
- Determination of the capacity in number of devices supported per km2 of the system depending on a few example orbit configurations.
- Determination of the user-plane latencies in the same example orbit configurations
- Studying methods to increase the capacity and lower the latencies. Optionally also UE enhancements focused on battery life.

Descripció

Context

The Nokia Aalborg department is part of the Nokia Standards organization, which supports development of 3GPP Radio Access specifications.

 

Project

In LEO based Non-Terrestrial Networks the UE needs to determine its location rather frequent and needs to read the System Information, broadcasted by the network, rather often due to the information changing or due to the fact that mobility events happen. Furthermore, in deployment scenarios with non-continuous coverage the UE may end up searching for cells unnecessary a large part of the time. In this study the energy consumption of an NTN UE needs to be analyzed and potential improvements studied and evaluated. Areas of improvement include neighbor cell measurements, SI acquisition, and user data transmission.

Tipus d'estada:

Descripció

Context

The Nokia Aalborg department is part of the Nokia Standards organization, which supports development of 3GPP Radio Access specifications.

 

Project

3GPP Non-Terrestrial Networks rely on GNSS with rather high accuracy in the UE for synchronization to the system. This has as unfortunate consequence that NTN does not function very well indoor. In this project the target is to study methods to overcome the high dependency of GNSS (either replacing GNSS or enhancing GNSS) and evaluate their performance. Alternatively, it can be studied how to mitigate the impact on the network/performance if the GNSS position is inaccurate.
