| Resumen: | This study presents a new approach for generating the symmetrical plan curve of a double-curved antenna reflector’s radiation pattern as an alternative to optimizing it when the primary radiation source has a given pattern. The results obtained are compared with those achieved using a source with a different characteristic, clearly indicating the potential to minimize the reflector surface area through illumination with a specific characteristic. Moreover, diffraction calculations for an antenna including a reflector that employs the calculated vertical profile derived from a primary radiation source characterized by a given beam pattern are presented. This analysis considers two cases: one with horizontal polarization and the other with vertical polarization. Simulation results are provided for the diffraction calculation of a reflector with radiation characteristics that employs a sectorial horn antenna with directivity characteristics. In this setup, the angular limits of the reflected beam are sequentially adjusted, allowing the changes in the directivity characteristic to be observed and discussed to determine the optimal configuration for the intended application. |
