We present the design of a full TX/RX terminal with dual switchable polarization based on the Metascreen technology, for Ka-band operations. The two screens, which exploit the Pancharatnam-Berry phase technique, have been optimized in order to scan a highly-directive beam with reduced level of the grating lobes. Preliminary experimental results show that this technology can produce beam-steering antennas with high radiation efficiency greater than 80%.

Abstract
We present the design of a full TX/RX terminal with dual switchable polarization based on the Metascreen technology, for Ka-band operations. The two screens, which exploit the Pancharatnam-Berry phase technique, have been optimized in order to scan a highly-directive beam with reduced level of the grating lobes. Preliminary experimental results show that this technology can produce beam-steering antennas with high radiation efficiency greater than 80%.
