A Dual-Polarized Magneto-Electric Dipole Antenna for Application to N77/N78 Band

A novel dual-polarized magneto-electric dipole antenna is developed for the next 5G wireless communications. The antenna is composed of four fishtail-shaped patches horizontally placed and four vertically placed patches shorted to the ground. The operation frequency band of the studied antenna is ranged from 3.05 to 4.42 GHz with SWR ≤1.5, covering the entire N77/N78 band for sub-6GHz 5G wireless communications. The measured gain varies from 7.09 to 9.36 dBi with high front-to-back ratios, meanwhile, very stable HPBWs at both horizontal plane (H-plane) and vertical plane (V-plane) within the frequency band of interest are found for the two polarizations, showing a promising candidate of this antenna for sub-6GHz 5G wireless communication applications.
