“…Furthermore, artificial magnetic conductors have also drawn some interest toward wideband and high-gain applications. In Malhat et al, 13 cylindrical DRA backed by plasma artificial magnetic conductor as a ground plane is investigated. A study on the phase reflection properties of the metamaterial using capacitively loaded loops-based artificial magnetic conductor slab is carried out in Erentok et al 14 In Saed and colleagues, [15][16][17] low-profile DRAs are proposed for a comparison between DRA and traditional microstrip patch antenna.…”

A wideband low-profile chamfered rectangular dielectric resonator antenna (RDRA) with high gain is proposed for sub-6 GHz 5G new radio band applications. RDRA is excited with microstrip cross-slot aperture coupling which is employed on the substrate. The dielectric resonator antenna with low-profile produces unwanted back radiation. The reflector placed at the bottom side of the RDRA is accountable for gain improvement on boresight direction by reducing back radiation. Slits, introduced on the copper layer, help to control the phase difference between direct waves and reflected waves.A rectangular stub is added to microstrip feed to enhance the impedance matching between excitation port and the antenna. The proposed antenna offers 2.74-4.35 GHz impedance bandwidth and 9.1 dBi peak gain. The proposed design is fabricated and experimentally verified.
