The antenna must adhere to more stringent requirements, including multi-band operation, high performance, and compact design, since it is the primary component of satellite communication systems. A shared-aperture antenna based on structural reuse is a viable method for attaining multi-band functionality of satellite communication systems and improving platform space usage. The development of multi-function antennas, antenna size reduction for shrinking, and cost reduction are all greatly impacted by shared-aperture technology. Because of the significance of L-band applications, the development of circularly polarized (CP) antennas has grown in importance. Because of their compensations, which include lower multipath losses and polarization mismatch, CP antennas are essential for many wireless applications, such as GNSS, satellite communication, and indoor wireless systems. This paper proposes a novel dielectric resonator array antenna. The shared-aperture feature is established by merging the dielectric high-frequency resonators in the annular dielectric low-frequency resonators. By controlling the phase difference between the degenerate modes, the low and high frequency orthogonal circularly polarized waves are created. The impedance matching is improved by optimizing the thickness of the circular cylindrical dielectric resonator. The sequential rotation method is used to design the array antenna. Simulation results show that the proposed dielectric resonator array antenna has superior performance and improved polarization characteristics as compared with existing methods.
