Bandwidth Enhancement of Low-Profile Metasurface Antenna Using Nonuniform Geometries
IEEE Open Journal of Antennas and Propagation, 2023 Artificial magnetic conductor metasurface antennas are investigated using a robust, surrogate-assisted, differential evolution optimization technique. Using a uniform metasurface array configuration as a starting point, multiple array configurations are ...

Power balance and efficiency of metasurface antennas [PDF]
Scientific Reports, 2020 AbstractThis paper presents two methods for the efficient evaluation of the power balance in circular metasurface (MTS) antennas implementing arbitrary modulated surface impedances on a grounded dielectric slab. Both methods assume the surface current in the homogenized MTS to be known.

ALL-TEXTILE ON-BODY METASURFACE ANTENNA
Progress In Electromagnetics Research M, 2022 In this work, a novel all-textile washable metasurface antenna is designed for WBAN/WLAN and mid-band 5G applications. Metasurface antenna is obtained by implanting SRR (Split Ring Resonator) metamaterials that show left-hand characteristics to the patch plane.

Designing Metasurfaces to Manipulate Antenna Radiation
2021 XXXIVth General Assembly and Scientific Symposium of the International Union of Radio Science (URSI GASS), 2021 Designer manipulation of light at the nanoscale is key to several next-generation technologies, from sensing to optical computing. One way to manipulate light is to design a material structured at the sub-wavelength scale, a metamaterial, to have some desired scattering effect.

Metasurface Antennas: Efficiency versus Bandwidth [PDF]
2021 15th European Conference on Antennas and Propagation (EuCAP), 2021 Two methods are proposed for the accurate and fast analysis of the efficiency of arbitrarily modulated metasurface (MTS) antennas. The surface current on the MTS is expanded into entire-domain basis functions. The first method uses a Fourier-Bessel basis and relies on the Poynting theorem, while the second approach is based on the calculation of the ...

Frequency-Reconfigurable Antenna Using Metasurface
IEEE Transactions on Antennas and Propagation, 2014 A frequency-reconfigurable antenna designed using metasurface (MS) to operate at around 5 GHz is proposed and studied. The frequency-reconfigurable metasurfaced (FRMS) antenna is composed of a simple circular patch antenna and a circular MS with the same diameter of 40 mm (0.67 λ) and implemented using planar technology.
