In the wake of intense research on metamaterials the two-dimensional analogue, known as
metasurfaces, has attracted progressively increasing attention in recent years due to the …

This paper provides an overview of fractal antennas and metasurfaces, exploring their
design principles, performance, and applications. Fractal antennas, incorporating self …

A Minkowski fractal-shaped patch is proposed for the design of a reduced-size reflectarray
element. The intrinsic miniaturization capability of the fractal geometry is fully exploited by …

Fractal geometries are appealing in all applications where miniaturization capabilities are
required, ranging from antennas to frequency selective surfaces (FSS) design. Recently …

This study reports investigations into phase characteristics of a unit cell of a single-layer
microstrip reflectarray exploiting fractal geometries. The aim is to have the phase range …

Gap surface plasmon (GSP) based metasurfaces, consisting of a subwavelength thin
dielectric spacer sandwiched between a metal film and an array of metal nanobricks, have in …

In recent years reflectarray antennas have become very popular research area for scientists
to overcome their limitations which are the narrow band of the radiating elements and the …

This paper presents analysis and design of the X-band Reflectarray using a three-
dimensional EM simulation based-Multilayer Perceptron Neural Network (MLP NN) model …

The paper reviews some of the relatively recent, and older reflectarray antenna designs in
the literature, that comprised a single layer of substrate and unit cell, as well as multiple …
