About this opportunity:

Shape the future of advanced antenna technology with Ericsson! As a Master’s Thesis Student, you’ll contribute to the next generation of 5G and 6G antenna systems by innovating cost-effective and high-performance RF interface solutions. Modern mobile antennas are increasingly complex, often using Active Electronically Scanned Arrays (AESA) that integrate multiple radio functions. At operational frequencies between 3 GHz and 10 GHz, flexibility in connecting either to an antenna or to a filter can be key for system adaptability and performance.

In this thesis, you will explore how to design RF connector and interface solutions that meet stringent EMC (Electromagnetic Compatibility) requirements while maintaining exceptional RF performance. One intriguing possibility, yet to be deeply explored, is integrating the connector directly into the shield cover — potentially eliminating the need for traditional EMC gaskets. Your research could help reduce interference, simplify design, and improve manufacturability for future radio-antennas.

What you will do:

• Investigate different types of interfaces and connectors for array antenna applications.
• Assess mechanical tolerances and forces required to connect all elements reliably.
• Verify expected electrical performance through 3D simulations using Ansys HFSS or Keysight ADS.
• Explore the feasibility of integrating the connector into the shield cover to remove the need for separate EMC gaskets.
• If time allows, perform physical testing and evaluation of selected designs.

The skills you bring:

• Enrollment in a Master's degree program in Electronics Engineering or equivalent.
• Solid knowledge of microwave circuit design.
• Familiarity with simulation tools such as Ansys HFSS, Keysight EMPro, or equivalent.
• Analytical mindset and ability to assess technical trade-offs.
• Capability to work collaboratively in an agile project team.
• Interest in combining mechanical design considerations with RF engineering.
