Abstract
This paper presents a metamaterial approach based ultra-wideband patch antenna using a different split-ring resonator structure. The proposed split-ring resonator is constructed on a 0.43mm thick RT Duroid substrate above a partly covered ground plane. The radiating element comprises of a rectangular geometry with arc-shaped structures at the shorter edges, with an overall dimension of 39x30 mm2. The proposed antenna provides a much favorable radiation pattern with a very efficient impedance matching across a wide bandwidth of 3-44 GHz, making it highly suitable for its operation at and beyond ultra-wideband applications and 5G communications. This paper discusses the antenna's design and the parametrical studies performed using available simulation tools.

An Overview of the Theory and Applications of Metasurfaces: The Two-Dimensional Equivalents of Metamaterials

TL;DR: Metamaterials are typically engineered by arranging a set of small scatterers or apertures in a regular array throughout a region of space, thus obtaining some desirable bulk electromagnetic behavior as mentioned in this paper.

Metamaterial-based efficient electrically small antennas

TL;DR: In this paper, a metamaterial paradigm for achieving an efficient, electrically small antenna is introduced Spherical shells of homogenous, isotropic negative permittivity (ENG) material are designed to create a resonant system for several antennas: an infinitesimal electric dipole, a very short center-fed cylindrical electric dipoles, and a coaxially-fed electric monopole over an infinite ground plane.
