Design, manufacture and measurement of a low-cost reflectarray for global earth coverage [PDF]

open access: yes, 2016
In this work a low-cost reflectarray with isoflux pattern for global Earth coverage is designed, manufactured and measured at 30GHz. The isoflux template is mathematically derived for a generic satellite and then particularized for a geostationary orbit.
