| Sumario: | [EN] Nowadays, due to the fast development of wireless communication systems, the need to have radiating elements has arisen. These elements allow an efficient radiation of electromagnetic waves that transmit the information among the different points of the system. Owing to this growing demand and based on certain requirements, several prototype antennas fabricated with planar technologies such as PCB "Printed Circuit Board" and LTCC "Low Temperature Co-fired Ceramic" are presented in this thesis. Every proposed prototype is presented as a solution for a project which requires an antenna with specific characteristics. Based on the requested specifications such as working frequency, bandwidth, polarization type, size and shape, the most appropriate design alternatives were selected. For satellite communications at 5.8 GHz, two types of antennas with circular polarization are proposed. The former is a square patch with a diagonal slot, the latter is a polarization reconfigurable antenna fabricated with LTCC technology. For the operation in Ku band at 17 GHz, slot arrays with substrate integrated waveguide technology were proposed, whereas for vehicular applications, monopole antennas were the better solution due to the restrictions in the form and space available for assembly. In addition, due to the growing interest in the applications operating at no licensed frequency bands, patch antenna arrays conformed in a cylindrical shape to operate at 2.4 GHz and 5.8 GHz, were designed. These arrays will be placed in UAVs. Each proposed design meets with the required specifications for the different projects such as: appropriate matching levels, radiation patterns according to the application, specific dimensions and material type |
