Reflectarray for K/Ka Band Terminal Antenna

Autor: Encinar Garcinuño, José Antonio, Barba Gea, Mariano

Different satellite systems have been defined to provide broadband communications and internet access in remote geographical areas in Ka band (20-30 GHz) [1-2], being the up-link at 30 GHz and the down-link at 20 GHz. Costeffective antennas are requi
