Metallic Metasurface Antennas for Space
12th European Conference on Antennas and Propagation (EuCAP 2018), 2018In metasurface (MTS) antennas, a surface-wave (SW) is gradually radiated by modulating an equivalent reactance tensor in the aperture plane. Such modulation results in the (-1) indexed Floquet mode entering the visible region, thus becoming a leaky-wave (LW) mode with curvilinear phase-contour.

A cylindrical metasurface antenna
2017 IEEE International Symposium on Antennas and Propagation & USNC/URSI National Radio Science Meeting, 2017We introduce a cylindrical metasurface antenna highly suitable for wireless communication towers. The antenna was designed to operate at 7.2 GHz. The design concept is based on constructive phase interference arising from the radiation of all elements comprising the metasurface.

Single-Feed Near-Field Excited Quad-Beam Metasurface Antenna
IEEE Antennas and Wireless Propagation LettersIn this letter, we propose the design of a single-feed low-profile digitally coded metasurface antenna for generation of quad-beam radiation. The design procedure involves initial synthesis of the desired reflection phase profile using far-field plane ...

Beam Scanning Metasurface Antennas
2018 IEEE International Symposium on Antennas and Propagation & USNC/URSI National Radio Science Meeting, 2018Metasurface (MTS)antennas have been shown to be a versatile class of planar antenna. In particular, they allow for beam shaping and pattern control through the modulation of the boundary conditions, while keeping unchanged the overall antenna structure. This feature makes them suitable for dynamic reconfiguration.

Efficiency of Metasurface Antennas
IEEE Transactions on Antennas and Propagation, 2017Different types of efficiencies are introduced for metasurface (MTS) antennas based on single point-source excitation: 1) the feed efficiency $\varepsilon _{\mathrm{ feed}} $ is the power delivered by the feed to surface wave (SW) over the input power; 2) the tapering efficiency $\varepsilon _{\mathrm{ tap}} $ quantifies the deviation with ...

Miniaturized Wideband Metasurface Antennas
IEEE Transactions on Antennas and Propagation, 2017The single- and dual-layer metasurfaces are proposed to miniaturize a low-profile wideband antenna. The single- and dual-layer metasurfaces consist of one and two square patch arrays, respectively, both supported by grounded dielectric substrate to form the waveguided metamaterials.
