| Popis: | This paper presents some recent developments in multiple beam antennas (MBAs) based on reflectarrays for communication satellites in K-and Ka-bands. The existing high through put satellites commonly employ four reflector antennas to provide cellular coverage formed by multiple spot beams in a four color scheme. Reflectarray antennas are proposed as an attractive solution for the design of novel MBA configurations to produce multi-spot coverage with a smaller number of apertures than conventional MBA systems based on reflector technology. Single and dual reflectarray configurations have been considered for this purpose, exploiting the reflectarrays’ ability to produce independent beams in different polarizations and frequencies. |
