A Dual-Polarized Wide-Beamwidth Magneto-Electric Dipole Antenna for the Fifth Generation Mobile Communications

In this paper, a dual-polarized wide-beamwidth magneto-electric (ME) dipole antenna for the fifth generation (5G) mobile communications is proposed. The proposed ME dipole antenna is printed on several dielectric substrates for easy fabrication. By applying a quadrate fence around the ME-dipole antenna, wide-beamwidth characteristics for both E- and H-planes can be obtained in dual linearly polarized directions. The proposed antenna realizes a half-power beamwidth (HPBW) of 129.1 ° in E-plane and another 100.4° in H-plane at 3.4 GHz, while 151.6° in E-plane and 94.2° in H-plane at 4.9 GHz can also be achieved. An overlapped impedance bandwidth (<; -10 dB) between the two ports of 63% (2.76-5.3 GHz) with gain of approximately 5 dBi can be attained.
