Long-period statistics of the power distribution of a multi-beam reconfigurable antenna for satellite broadcasting over the European area

The paper presents long period statistics of power distribution related to a multispot reconfigurable antenna for satellite broadcasting working over the European area. The irradiation of the antenna is optimized following a set of procedures already described in literature, and based on the joint use of two standard data sources: the European Centre for Medium Range Weather Forecasting (ECMWF) and the Meteosat Satellite. The paper analyzes the statistical distribution of the power injected in the various beams of the antenna during four years of continuous work (1997-2000). The statistics are compared with the fixed amount of power granted to each beam when the available power is subdivided statically, depending on the average value of attenuation affecting the area of service.
