Estudio de reflectarray multihaz para aplicaciones de satélite en banda Ka utilizando discriminación en frecuencia

Abstract

This contribution describes a design concept based on beam squint effect in printed reflectarrays that allows to produce multiple contiguous beams at 19.5 and 20 GHz, by discriminating in frequency. A 1.6-m reflectarray has been proposed to produce 10 beams separated 0.5 degree using five feeds with frequency reuse. The simulated radiation patterns show a peak gain better than 47.6 dBi, with side-lobe levels close to -24 dB. The proposed concept can be suitable for multiple spot beam satellites in Ka-band
