This book presents a comprehensive insight into the design techniques for different types of
CP antenna elements and arrays In this book, the authors address a broad range of topics …

The growing demands of advanced future communication technologies require investigating
the possible enhancement in the current features of a reflectarray antenna. Its design and …

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 …

A broadband low-profile high-gain folded transmitarray antenna (FTA) is proposed to
generate orbital angular momentum (OAM) with circular polarization. A chiral metasurface is …

This communication presents a wideband high-efficiency circularly polarized (CP) folded
reflectarray antenna (FRA) based on the CP selective surface (CPSS). The proposed …

Design and implementation of a dual-band single layer microstrip reflectarray are presented
in this communication. The proposed reflectarray operates in two separated broad frequency …

This communication reports a broadband circularly polarized (CP) reflectarray operating at-
band. An asymmetric dual-polarized magneto-electric (ME) dipole is proposed as the …

A broadband linearly polarized single-layer reflectarray antenna constructed by element
cells of triple gapped rings with phase-delay lines (TGR-PDLs) attached to the outer one is …

A center-fed single-layer, dual-band reflectarray antenna is presented in this letter. Each
element in this reflectarray antenna consists of a square ring and a patch, with slots on it …

A novel broadband unit cell is proposed in this letter. This new cell element consists of three
coupled circular rings where four quasi-spiral delay lines are connected to the outer ring to …
