Circularly Polarized Dielectric Resonator Antenna Arrays with Fractal Cross-Slot-Coupled DRA Elements
In the design of circularly polarized (CP) dielectric resonator antenna (DRA) arrays, the regular-shaped DRAs with simple feeding configurations are Maintenance Mat mostly used as array elements to make the design procedure more efficient.However, such array element DRA usually achieves only about 6% axial ratio (AR) bandwidth.In this paper, a CP D
