註釋The research for sampling biological samples has been moving forward looking for to get out the best of sensibility and methods that don't damage the samples or rather destroy them. A branch of methods that can possible arrive a good compromise between those two are microwave sensors that get data from permittivity analysis and don't cause any sample damage and also have a good sensibility. In this project we were focusing on researching a type of microwave technology called SIW that is able to reproduce a waveguide in a much smaller size. The aim was to prove that with a SIW we could create an equivalent waveguide sensor that had the same performance but much smaller size and is easier to create. The results obtained with simulations and testing give us a good approach to implement this technology for sensors. We determine that although the range of operation and losses that restrict a good performance, it is possible to determine the permittivity by comparing measured data with simulations and previous research papers.
