“…Single feeding usually requires simple configuration and less space. It enables 90° phase difference excitation with some feeding arrangement like 45° inclined feed, single parasitic patch, and Helix conductor have been reported in literature (Figure ). However, this single feeding approach gives smaller bandwidth.…”

This article outlines a compressive review on investigation carried out targeting to gain, circular polarization (CP), and mutual coupling reduction in dielectric resonator antenna (DRA). The DRA has already been created a separate position in antenna engineering domain because of its adept characteristics, such as wide bandwidth, high efficiency, low‐loss, and mainly 3D‐design flexibility which is rarely available in conventional antennas. In this context, the research on gain, circular polarization, and mutual coupling are quite interesting and being carried out from the last two decades. The ultimate aim of this article is to (i) give an overview of different techniques adopted in context to gain, CP, and mutual coupling reduction; (ii) give a compressive review of notable research carried out targeting to these three characteristics; and (iii) find out the research gap concentration for furtherance of the same.

“…In a modern wireless system, to transmit and receive the signals, circularly polarized (CP) antennas are used. Therefore, the CP antenna attracts a huge attention due to its powerful features such as it suppress multipath fading effects, improve signal power at the reception, improved mobility, weather penetration and its freedom from the orientation angle between the transmitting and receiving antennas . To produce circular polarization in DRAs, three techniques have been reported in the literature such as single point feed, multiple point feed, and sequential rotation technique .…”

In this article, a cylindrical dielectric resonator antenna (CDRA) excited by a 45° rotated square ring slot with a T‐shaped coupling microstrip line is investigated for circularly polarized (CP) operation. The proposed antenna shows the dual band characteristics and the lower band is generated due to T‐Shaped microstrip line and upper band is due to CDRA. In the proposed antenna, the two degenerate broadside orthogonal modes ( HE11δx mode and HE11δy mode) of the CDRA are used to realize CP radiation. The prototype of the proposed antenna has been fabricated and tested. The measured |S11| bandwidth in the lower and upper band is found to be 14.65 and 19.86%, respectively. The measured 3‐dB axial ratio bandwidth of 1.46 and 6.01% is achieved in the upper band only. Proposed antenna has been found suitable for wireless application.

“…In addition, CP fields are less sensitive to the propagation effect than LP fields. Due to these numbers of attractive features, the CP system is widely used in satellite communications, mobile communication, navigation systems, radar system and global positioning system [26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45]. To obtain more information from targets, the polarization used in radar system is circular [46].…”

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.
