Circularly polarized (CP) antennas are becoming a key technology for wireless communication systems because of their several inherent advantages over linearly polarized (LP) antennas. Enhanced axial ratio (AR) bandwidth, low profile, lightweight, and ease of fabrication are some requirements that must be addressed while designing CP antennas. Electromagnetic bandgap (EBG) structures are gaining much popularity among microwave and antenna engineers because of their unique properties, such as reflection phase bandgap and surface wave bandgap. In recent years, many author have proposed embedding polarization-dependent EBG (PDEBG) structures for designing CP antennas. Based on an extensive literature review, it is observed that embedding PDEBG structures significantly enhance the AR bandwidth while preserving a compact and low-profile antenna geometry. This paper presents a comprehensive conceptual framework and a generalized review of CP antenna designs employing PDEBG structures, highlighting their operating principles and design trends.
Polarization of an antenna refers to the orientation of the electric field vector of the radiated wave in the far-field.
