This paper describes basic of circular polarization, fundamental concepts, theory and review study of the circularly polarized dielectric resonator antenna (CP DRA) over the last three decades. Wide 3 dB axial ratio bandwidth, impedance bandwidth, compactness and high gain are demonstrated on the basis of attainable performance of CP DRA designed. The latest techniques for generating the circular polarization as well as enhancing the performance are also covered. The latest advancements in single-point feed, multiple point feed and sequential rotation CP DRA design techniques are also investigated. CP DRA catches the potential application in the Satellite communication, mobile communication, GPS, WLAN, WIMAX, Mobile communication and Radar system.

“…The concept of using metal parasitic strip attached on DRA surface was first considered in [8] and subsequently its application has been extended to different geometries like cylindrical [9], rectangular [101 and hemispherical DRAs [1114 [13]. In these investigations [9]- [12] the parasitic strips were used to produce circular polarization with wider bandwidth.…”

Dielectric resonator antenna (DRA) has been proposed recently as a viable new way to build antenna in view of some of the advantages they offer. One recent trend in DRA research focuses on using composite and hybrid structures. Some considerable investigations are already underway showing quite interesting and significant features. A brief review of the topic is presented in this article. A general discussion comparing a microstrip patch and a DRA is provided in the beginning. Some state-of-the-art developments and associated challenges in the DRA design and applications are also discussed.

“…This feature is very useful in various communication systems. There are different mechanisms, by which a circularly polarized DRA can be obtained, such as dual coaxial probe [13], dual conformal strip [14], with parasitic strips [15], rotated sequential feed [16], aperture feed [17], spiral slot [18], and special shaped DRA. The method of producing circular polarized radiation using cylindrical DRA with helical exciter has been reported in [19] recently.…”

Abstract-A novel (2 × 2) high gain circularly polarized rectangular dielectric resonator antenna array integrated with helical-like exciter is proposed. The array offers a maximum gain of 12.9 dBi at the operating frequency. The circular polarization is obtained by incorporating helical-like exciter in the array structure. A prototype of the proposed configuration integrated with helical-like exciter has been fabricated and tested, and the idea has been verified. A good agreement has been obtained between the measured and simulated results.
