Considerations on the design and analysis of a shaped reflector antenna for nodal stations in metropolitan areas

Considerations on the design and analysis of a shaped reflector antenna synthesized for a cosecant squared beam in the vertical plane and azimuthal uniform radiation, for use in nodal stations, are reviewed. Emphasis is given to the global interpolation of arbitrarily located sets of data points, as furnished by the synthesis technique. In particular, the applicability of cubic pseudosplines is explored in conjunction with the physical optics current integration method of analysis, and results compared with those previously established for the implementation of quintic pseudosplines
