Abstract: | A circularly polarized rectangular dielectric resonator antenna (DRA) has been designed (3.7–4.2 GHz) for WiMAX, satellite, and sub-6 GHz 5G NR band communications. A new T-shaped monopole has been used to excite the rectangular DRA. Using proposed conformal metal strip, the higher-order degenerate modes TEδ13x and TE1δ3y have been excited to achieve circular polarization (CP) with improved gain. Further, the bandwidths enhancement has been achieved by placing a parasitic patch of optimized height and width at a specific distance from T-shaped strip on DRA surface to cover the desired frequency band. A signaficant enhancement of ~73% in the impedance-matching bandwidth and ~75.5% in axial ratio (AR) bandwidth has been achieved. The |S11|≤10 dB over a wide bandwidth of ~17.3% has been offered by the antenna. A broad axial ratio bandwidth of ~17.2% along with a useful gain of ~6.32 dBic has been provided by the antenna. The antenna designing and optimization has been carried out using CST® Microwave Studio. A reasonable agreement between simulated and measured results has been observed. |
