En décembre 2018, la diffusion par satellite de la télévision ultra haute définition (UHDTV) 4K/8K débutera au Japon. Il sera fourni dans la bande 12 GHz (11.7 à 12.75 GHz) avec des polarisations circulaires droite et gauche. BSAT-4a, un satellite utilisé pour la diffusion de télévision UHD, a été lancé avec succès en septembre 2017. Ce satellite dispose non seulement de transpondeurs à polarisation circulaire droite et gauche dans la bande 12 GHz, mais également d'un transpondeur expérimental dans la bande 21 GHz. La bande 21 GHz (21.4 à 22.0 GHz) a été attribuée comme liaison descendante pour le service de radiodiffusion par satellite dans les Régions 1 (Europe, Afrique) et 3 (Asie-Pacifique) de l'UIT-R. Pour recevoir les services fournis sur ces deux bandes de fréquences et avec double polarisation, nous avons mis en œuvre et évalué une antenne à réflecteur parabolique double bande et double polarisation circulaire alimentée par des réseaux d'antennes microruban dans les bandes 12 et 21 GHz avec une structure multicouche. L'antenne est utilisée pour recevoir les signaux dans les bandes 12 et 21 GHz des satellites en orbite. Les résultats mesurés et expérimentaux prouvent que l'antenne proposée fonctionne comme une antenne à double polarisation dans ces deux bandes de fréquences et a des performances suffisantes pour recevoir des émissions par satellite.

Abstract: In December 2018, satellite broadcasting for 4K/8K ultra-high-definition television (UHDTV) will begin in Japan. It will be provided in the 12-GHz (11.7 to 12.75GHz) band with right- and left-hand circular polarizations. BSAT-4a, a satellite used for broadcasting UHDTV, was successfully launched in September 2017. This satellite has not only 12-GHz-band right- and left-hand circular polarization transponders but also a 21-GHz-band experimental transponder. The 21-GHz (21.4 to 22.0GHz) band has been allocated as the downlink for broadcasting satellite service in ITU-R Regions 1 (Europe, Africa) and 3 (Asia Pacific). To receive services provided over these two frequency bands and with dual-polarization, we implement and evaluated a dual-band and dual-circularly polarized parabolic reflector antenna fed by 12- and 21-GHz-band microstrip antenna arrays with a multilayer structure. The antenna is used to receive 12- and 21-GHz-band signals from in-orbit satellites. The measured and experimental results prove that the proposed antenna performs as a dual-polarized antenna in those two frequency bands and has sufficient performance to receive satellite broadcasts.
