Abstract
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 × 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°. 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.
