I developed my M.Sc. Thesis in collaboration with Thales to improve the mobile service provided on trains. The work consisted in analysing the performance of antennas mounted on trains for mobile communications and the influence of the surrounding environment on them, such as HVAC (Heating, ventilation, and air conditioning) structures, using different mobile communications systems like GSM-R, LTE-R and BBRS.Some of the software tools used: Antenna Magus (Antenna design software), CST Studio (Electromagnetic simulation software) and Matlab (Numerical computing software).

I wrote my thesis as a member of GROW (Group for Research on Wireless) which is led by Professor Luís Correia and it has several Ph.D. and M.Sc. students. GROW has provided me the opportunity to interact with different researchers, in order to exchange ideas and perspectives about our work, as well as, to discuss new developments in the field of Mobile Communications.
