Reflectarray antennas have attracted special attention for implementing high gain antennas
as they combine some advantages of phased arrays and reflectors, such as low losses …

This paper presents recent advances on reconfigurable reflectarrays at the University of
Perugia. In particular the activities carried out in the framework of the European Network of …

Reflectarray antennas (RAs) have the ability to combine the advantages of both traditional
parabolic reflector and phased array antennas without the need for feed network designs …

ABSTRACT A novel single‐layer microstrip reflectarray element with fractal structure is
proposed. Ansoft HFSS is used to analyze the reflect phase for the fractal element in …

A new approach to analyse reflectarray cells is presented, which allows mutual coupling
effects to be realistically accounted for by simulating each radiating cell with its actual …

An efficient artificial neural network (ANN) approach for the modeling of reflectarray
elementary components is introduced to improve the numerical efficiency of the different …

This article presents a compact frequency selective surface (FSS) design which is capable of
rejecting both bands of Wi‐Fi. The proposed design is evolved from a patch‐slot topology …

This paper presents a printed reflectarray with dual-polarization capabilities. The array
element is a square patch loaded with crossed slots. Both the size of the patch and that of …

In this paper, a wideband microstrip antenna for X-band (8.2 GHz--12.4 GHz) applications is
introduced. First, simple patch antennas are studied. The resultant design demonstrates …

Innovative and high-performance antenna systems are required by the increasing demand
of bandwidth and service quality in modern communication systems, as well as in a number …
