Master Thesis: Radio Interface of Microwave Antennas

Job Description

Date: Oct 31, 2019

Do you want to do your thesis with us in Göteborg?

Would you like the chance to do your thesis together with one of the world’s leading technology companies? We are on a quest to enable communication for everyone and everything and we believe that we do that by being as innovative as possible. If you want to help us to be even more innovative – then you are on the right track!

 

We want you to become a part of a truly global company working across borders in 180 countries, offering a diverse, performance-driven culture & an innovative & engaging environment where employees enhance their potential every day. Come and learn and grow with us at Ericsson.

 

Background

Integrated microwave antennas and radios are used to transfer data in mobile transport networks. It’s a cost-efficient solution for fiber cable. The radio data is transmitted in a microwave hop.  Simplified, a hop consists of two antennas including radios mounted in a tower on two different locations wirelessly communicating with each other.

 

It’s essential for the microwave hop that RF and water leakage are prevented since it causes disturbances. RF leakage causes signal/data loss and RF interference while water leakage can possibly short circuit the radio. Any disturbances are costly for Ericsson, the operators and the end customers and could be devastating if the hop is down. Therefore, this Master Thesis will focus on the interface between the radio and the microwave antenna.

 

Description

Today’s radios and antennas have a single waveguide port and it’s essential that the waveguide ports can repeatedly be properly aligned against each other using a robust interface to fulfil requirements on environmental sealing, RF leakage etc. It’s also important to consider the fact that the radio interface is assembled on site by installers who have varied knowledge and experience. Lastly, you need to consider cost and modularity.

 

We would like to see continuous prototypes/mockups of different concepts during the project. These can be printed in one of our 3D printers we have inhouse or ordered from one of our suppliers when there is a need for a machined prototype.

 

As an outcome of the Master Thesis, we expect a concept of the interface design of the radio and the antenna. Preferably it is shown both in forms of CAD-files and drawings together with a prototype that demonstrates the concept.

 

In addition, we also would like you to propose a set of verification methods that we can use during design verification of this interface to see that it works as intended both during the design phase but also during volume production.

 

Requirements/ key qualifications

Master student within Product Development, Mechanical Engineering or similar.

 

We believe this thesis is done by two students working as a team together with support from us.

 

Application

If you feel interested, please send in your application as soon as possible. The start date can be adjusted to both your and the business needs – the intention is to start in January or February 2020.
