Compact Hight-Gain DRA Antenna Array At 28 GHz

In this paper, a compact, wideband, high gain, dielectric resonator antenna (DRA) array is proposed. The antenna structure works at 28 GHz band which makes it suitable for 5G wireless communications. The proposed antenna structure uses an array of four rectangular DRAs to enhance the gain. Simulation results show that the antenna design covers about 2 GHz of bandwidth (S11<; -10 dB) while delivering high gain of 14.7 dBi.
