In this work, we analyze the design and construction of deferent kind of strain sensors based on patch antennas. The patch antenna strain sensor constitutes a device with a planar profile that changes its electrical parameters due to a load applied. The aim is to design and to produce a strain sensor based on patch antennas, which has suffered a modification in its design, and that exhibits performance improvements in comparison with a conventional patch antenna. It was examined deferent sensor design in order to identify how is the relationship between sensor design and its performance. All sensor model was analyzed by a numerical perspective, where a structural and electromagnetic analysis was carried for each sensor design, and it allowed to determinate which antenna has a better performance. Next, an optimization process was carried in order to and the most sensible sensor. Finally, it was validated the numerical result by an experimental tension test using specialized equipment and controlled environmental conditions. The results showed that the resonant frequency of the antenna has a maximum variation of 24;25 MHz and a sensitivity of 4 KHz= μe, with a relative error of 7.5 % in comparison with the simulation results. The work we done allowed to prove that there is a key relationship between the design's parameters and sensor performance, which can be employed to and the best sensor functionality according to specific requests
