Multibeam by Metasurface Antennas
IEEE Transactions on Antennas and Propagation, 2017We explore various possibilities for designing multibeam antennas using a single metasurface (MTS) aperture. Both single-source and multisource feeding schemes are considered. For the single-source case, two approaches are investigated. In the first one, the MTS aperture is divided into several angular sectors, each one devoted to the formation of a ...

A Dual-Polarized Omnidirectional Metasurface Antenna Designed via Characteristic Mode Analysis
IEEE Antennas and Wireless Propagation Letters, 2023A low-profile dual-polarized (DP) omnidirectional metasurface antenna is proposed in this letter. By conducting characteristic mode analysis on a metasurface, one mode with a vertically polarized (VP) omnidirectional radiation pattern and another one ...

Advanced Cloaking Metasurfaces for Wire Antennas
2021 XXXIVth General Assembly and Scientific Symposium of the International Union of Radio Science (URSI GASS), 2021We provide a review of our results on the design of mantle cloaking devices for antenna applications with an emphasis on our recent investigations in designing advanced cloaking metasurfaces. It is shown how such cloaking devices allow increasing the degrees of freedom in the design of conventional antennas with a significant enhancement of their ...

This chapter reports design and analysis methods for planar antennas based on modulated metasurfaces (MTSs). These antennas transform a surface wave (SW) into a leaky wave by means of the interaction with a MTS having a spatially modulated equivalent impedance.
