摘要：
Compact, low-profile metasurface-based wideband and wide dual-band circularly polarized (CP) dielectric resonator antennas (DRAs) are presented in this paper. The rectangular-shaped DRs are loaded over two different types of strategic 7 x 7 metasurface unit cells including a "+" shape metasurface for single-band and square-slotted shape metasurface for dual-band performance. The DRs are fed diagonally with a single perturbed probe feed which is placed at an appropriate angle of 29 degrees. Thus, the hybrid design combination of metasurface unit cells together with the angle of feed location from the center of DRs generates wideband CP radiation with enhanced 3-dB Axial Ratio (AR) and wide impedance matching bandwidths. Proposed antennas are successfully implemented and fabricated prototypes are measured demonstrating significant performance enhancement.
