Resumo:
This masters dissertation presents the design of a rectangular microstrip antenna with dual feeding, operating band and polarization. It operates at a frequency of 3.5 GHz with linear polarization, in the plane of the electric field (in fundamental mode (TMz100) – applied to 5G technology) and at a frequency of 5.2 GHz with linear polarization, in the plane of the field magnetic (in third order mode (TMz030) – applied to Wi-Fi technology). The antenna is formed from the orthogonal geometric superposition of two techniques, one that allows increased gain and other that allows the filtering of high-order modes. Based on the simulation and measured results, the antenna operated in two bands, 5G and Wi-Fi, with minimum isolation between ports of −16 dB. Ultimately, the functioning of each of the intermediate geometries was separately validated and, finally, the functioning of the final model.
