## 4 Conclusions and Future Scope  
This study presents a circularly polarized hybrid dielectric resonator antenna with an impressive return-loss (RL) bandwidth of 485 MHz (ranging from 4740 MHz to 5225 MHz) and an axial ratio (AR) bandwidth of 150 MHz (spanning from 4950 MHz to 5100 MHz). The proposed antenna achieves a peak gain of 7.03 dBic at 5 GHz, making it suitable for missile tracking, data link communications, and IEEE 802.11n WLAN applications. The paper discusses the composition of the antenna, the optimization of its feeding mechanism, and the generation of two orthogonal modes, along with relevant results. A prototype of the antenna has been fabricated, tested, and validated against simulation results. The novelty of this work lies in the combined probe feed mechanism, which integrates both the ring patch and the dielectric resonator element to produce circularly polarized radiation. However, there are limitations concerning return loss and axial ratio bandwidths. These limitations can be addressed in the future through the use of metasurfaces and optimized feed locations, which will be further explored.
