dc.description.abstractThis paper proposes a prism-shaped dielectric resonator (DR) -based antenna with circularly polarized (CP) characteristics for C-band wireless systems. This antenna comprised a prism-shaped DR and single-layer substrate. The prism-shaped DR is on the upper-side substrate. Besides, a rod-shaped probe was plugged into a DR and connected by an SMA connector on the lower-side substrate. A loop-shaped metasurface-enhanced reflector is employed to improve bandwidth (i.e., RLBW and ARBW) and antenna gain. A regularly spaced array of 7 × 7 loop-shaped metasurface unit structures is positioned on the upper substrate side. The simulation RLBW and ARBW results at 5.8 GHz (center frequency) are 34% (5.22 - 7.2 GHz) and 16% (5.27 - 6.2 GHz). This antenna radiates left-hand circular polarization with an optimal maximum gain at 5.5 GHz of 6.7 dBic, making it suitable for C-band wireless networks.
