Metasurfaces (MTSs) are versatile, technologically advanced new materials, which have proven their capability to be successfully employed for constituting variable impedance plane and enabling precisely controlled radiation from equivalent apertures for antenna applications. Among the several requirements that can be desired in Space Communications environment the possibility of obtaining shaped beams is one of the most demanding features, in this framework MTS antennas assume a key role. In this work two new designs of shaped beam antennas are presented. These implement a low-complexity data-downlink aperture for Ka-band LEO missions and, in the second example, a printed MTS is applied for pattern shaping of a Ku-band horn for global Earth coverage.

Abstract

Metasurfaces (MTSs) are versatile, technologically advanced new materials, which have proven their capability to be successfully employed for constituting variable impedance plane and enabling precisely controlled radiation from equivalent apertures for antenna applications. Among the several requirements that can be desired in Space Communications environment the possibility of obtaining shaped beams is one of the most demanding features, in this framework MTS antennas assume a key role. In this work two new designs of shaped beam antennas are presented. These implement a low-complexity data-downlink aperture for Ka-band LEO missions and, in the second example, a printed MTS is applied for pattern shaping of a Ku-band horn for global Earth coverage.
