## 1 Introduction
Inserting dielectric blocks beneath the patch can significantly reduce antenna size while still achieving the desired bandwidth and axial ratio for L-band applications [20]. Another design is a strip-line fed compact rectangular DRA with a top-loaded rectangular patch [21], which can possess various aspect ratios and produce circularly polarized radiation. Selecting an appropriate aspect ratio for the top-loaded rectangular patch allows for the division of the fundamental resonant mode of the rectangular DR antenna into two orthogonal degenerate modes (TE\({}^{\mathrm{x}}\)\({}_{111}\) and TE\({}^{\mathrm{y}}\)\({}_{111}\)), leading to circular polarization. A high-gain single-element hybrid DRA [22] composed of a microstrip and an elliptical-shaped dielectric ring has also been proposed for millimeter-wave frequency applications. This combination results in high gain, with an inverted T-shaped slot contributing to CP radiation. The aspect ratio and gain can be fine-tuned with the ring-shaped DR. The design has achieved a maximum impedance bandwidth of 12% and an axial ratio bandwidth of 10%, with a measured gain exceeding 9 dBi across the entire frequency band. The versatility of hybrid DRAs allows engineers to select various methods to achieve CP, tailoring antenna designs to specific application requirements. Metasurface-based CDRAs have been reported as an effective solution for enhancing gain [23] and achieving wide bandwidth [24] while maintaining circularly polarized radiation. These advancements leverage the unique properties of metasurfaces, allowing for improved performance metrics in wireless communication applications. A portion of this work has been submitted [25] for a conference focused on generating wideband dual-sense circular polarization. This paper presents a novel single-coaxial feed method designed to excite both circular ring patches and cylindrical dielectric resonator elements. This method creates two orthogonal modes that enable circular polarization radiation, offering a broad axial ratio (AR) bandwidth that spans the WLAN frequency range and supports high-speed data transfer. Initially, a basic cylindrical DRA is constructed using a rectangular substrate and ground structure, resonating at 4 GHz. The innovative probe-feed mechanism is asymmetrically positioned between the circular ring patch and the cylindrical DR element, facilitating high-gain CP radiation, which represents a significant advancement in the field. The proposed design involves a simple tuning technique that adds a circular ring patch to the basic DRA to achieve CP at the desired resonance frequency. Furthermore, this hybrid DRA is compared with other related hybrid antennas from the existing literature [23; 24; 26; 27; 28; 29; 30; 31]. The versatility, adaptability, and performance advantages of hybrid dielectric resonator antennas position them as a cutting-edge solution for modern wireless applications. As the demand for faster and more reliable communication continues to grow, these antennas are likely to play a crucial role in advancing communication technologies, providing a robust alternative to traditional antenna designs. The proposed paper is outlined with a comprehensive literature review in the introduction, detailed composition of design, parametric and field analysis, and prototype and measured results with detailed discussion.
