## 1 Introduction  
Bringing advanced technologies and high standards to upcoming wireless solutions, 5G is quickly becoming a reality. The 5G n79 band is a New Radio (NR) band within the Frequency Range 1 (FR1) with frequencies below 6 GHz. The center frequency of the 5G n79 band is 4700 MHz with an operating range of 4400 to 5000 MHz [1, 2]. There is a growing demand for wideband, high-gain antennas due to their compact size, light weight, and efficiency. Antenna polarization is also an important performance factor in modern communication systems. Dielectric resonator antennas (DRAs) are widely used because of their excellent features such as wide bandwidth and better radiation. These antennas have low losses and are more efficient than metallic antennas. DRAs come in different shape geometries, including cylindrical, rectangular, spherical, half-split cylindrical, disk, and hemispherical [3]. Circularly polarized antennas play essential roles in RFID, radar, WLAN, and satellite communication as they reduce multipath fading and have better weather adaptability. CP antennas are best for long-distance communications. With the rapid increase in usage and deployment of wireless networks, low wideband circularly polarized antennas are desired. Circularly polarized antennas are better than linearly polarized antennas because of their advantage of low cross-talk and better mobility [4]. Various wideband and multiband hybrid DR antennas are reviewed to identify the techniques used to generate CP [5]. Anelectromagnetic coupled hybrid DRA with a hexagonal split ring slot is presented in [6] for CP radiation. For wideband CP radiation, a rectangular DRA coupled with orthogonal slots and excited with a microstrip circular ring has been investigated [7]. Multi-functional CP antennas are essential for satellite communication, GPS, and other wireless systems that require a high degree of polarization purity and immunity to signal fading [8]. CP antennas often reduce multipath interferences and ease alignment between transmitting and receiving antennas. For CP radiation, a low-profile patch antenna inspired by metamaterials is proposed and studied [9]. The 2D metasurface has unique properties, including blocking and absorbing EM waves [10; 11]. Nowadays, planar metasurfaces are used for radio frequency and energy harvesting because of their advantages of negative permeability and refractive index [12; 13]. Loading metasurfaces (MTSs) is one of the effective strategies for increasing antenna bandwidth [14] and gain. It is possible to generate CP radiation from DR elements by changing the aperture feeding mechanism through an open-ended slot ground [15] and combining a conformal E-shaped patch with a probe feed [16]. A quasi-self-complimentary metasurface for CP radiation [17], a mushroom-like metasurface, and a DR element are combined in the first step to create a miniaturized and broadband response [18], and a rectangular-shaped DRA is designed and constructed using metasurface lens loading for enhanced gain [19]. For dual CP radiation applications, a wideband rectangular DRA with a penetrated probe feed loaded over a rectangular metasurface with a slot has been reported [20]. A similar approach is reported with a different perturbed probe feed at the edge of the rectangular DRA loaded on a plus-shaped unit-cell-based metasurface for wideband CP radiation applications [21]. This paper proposes a hybrid cylindrical DRA over a modified Minkowski fractal\(-\)shaped metasurface for broad CP radiation and provides a consistent gain of more than 5 dBic across the offered bandwidth. The proposed hybrid structure consists of a cylindrical dielectric resonator excited by a perturbed coaxial probe feeding mechanism and a metasurface designed to provide circularly polarized wideband radiation. A cylindrical DRA is placed over a modified Minkowski fractal\(-\)shaped metasurface, which consists of unequal rectangular\(-\)shaped cells with different indentation widths and lengths.
