It will start with a literature review of similar applications. Then the choice of design will be explained based on this literature. After that the simulation process that validates both our antenna and transition designs will be presented. Those simulations are carried out by CST studio suite. Then an overview of the fabricated pieces of our design will be presented. Finally the thesis ends with the measurements analysis and a comparison of those to the simulated results and what can be found in literature. The measurements are taken in UCL's Welcome lab facilities. At last it will evaluate our project's outcome, and state whether the design is exploitable or needs more tuning.SIWLens antennaSIW to waveguide transitiontext::thesis::master thesisthesis:37859
