In this study, a coplanar parasitic metallic strip has been employed to analyze the performance of dielectric resonator antennas (DRAs). The parasitic strip is positioned on the same plane as the 50Ω microstrip feed. By integrating the DRA with the coplanar strip and microstrip line, an impedance bandwidth of up to 17.33% is achieved at an optimal operating frequency of 2.77 GHz. Additional parameters such as return loss, impedance, polarization, and radiation behavior of the antenna are also examined. The antenna exhibits broad radiation patterns with low cross-polarization levels, confirming that it maintains linear polarization throughout the entire impedance bandwidth range.
