Modulated Metasurface Antennas for Space: Synthesis, Analysis and Realizations
G. Minatti,Marco Faenzi,Enrica Martini,Francesco Caminita,Paolo De Vita,David Gonzalez-Ovejero,Marco Sabbadini,Stefano Maci +7 more
TL;DR: In this paper, a planar antenna based on modulated metasurfaces (MTSs) is proposed for the first time for space applications, where an impedance-based amplitude synthesis of the aperture field distribution is presented.
Journal ArticleDOI
Multibeam by Metasurface Antennas
TL;DR: In this paper, the authors explore various possibilities for designing multibeam antennas using a single metasurface (MTS) aperture, both single-source and multisource feeding schemes are considered.
Journal ArticleDOI
Metasurface Antennas: New Models, Applications and Realizations
Marco Faenzi,G. Minatti,David Gonzalez-Ovejero,Francesco Caminita,Enrica Martini,Cristian Della Giovampaola,Stefano Maci +6 more
TL;DR: It is experimentally shown for the first time that metasurface antennas constituted by subwavelength elements printed on a grounded dielectric slab can have aperture efficiency up to 70%, a bandwidth up to 30%, and produce two different direction beams of high-gain and similar beams at two different frequencies, showing performances never reached before.
Journal ArticleDOI
A review on array mutual coupling analysis
TL;DR: An overview of mutual coupling analysis in antenna arrays is given in this paper, where the relationships between array impedance matrix and embedded element patterns, including beam coupling factors, are reviewed while considering general-type antennas; approximations resulting from single-mode assumptions are pointed out.
Journal ArticleDOI
Gaussian Ring Basis Functions for the Analysis of Modulated Metasurface Antennas
TL;DR: In this paper, the spectral and space-domain properties of planar metasurface (MTS) antennas are exploited for the efficient method of moments (MoM) analysis of MTS antennas, where the effect of the homogenized MTS is introduced in the integral equation as an impedance boundary condition.
