A Wideband Circularly Polarized Linear Parasitic Dielectric Resonators Antenna Array for 5G Applications

In this work a circularly polarized linear parasitic DRs (Dielectric Resonators) antenna array for 5G applications is presented. The symmetrical linear array consists of five DR elements. The proposed configuration has a central driven element fed with coaxial probe. Two parasitic elements on each side of the driven element make the arrangement parasitic and symmetrical. All the DR elements including the driven and parasitic elements have the same relative permittivity (dielectric constant) with 0.5λ inter elements spacing. The driven element has a thin micro-strip line stacking for impedance matching. The linear array has reduced ground plane for wideband operations. The simulated wideband operations make the proposed design a good candidate for the 5G applications. The proposed design gives 100% impedance bandwidth and 69% circular polarization bandwidth. The performance parameters show that the proposed design is a good candidate for 5G applications.
