Beamwidth Enhanced Broadband Dual-Polarized Magnetoelectric Dipole Antenna for 5G N78 Band
A beamwidth-enhanced broadband dual-polarized magnetoelectric dipole antenna for 5G N78 band is proposed in this letter. The structure of the proposed antenna is novel compared with conventional magnetoelectric dipole antennas. It is composed of folded and slotted magnetoelectric dipoles at the bottom, folded and slotted electric dipoles in the middle, several metal columns, four parasitic patches on the top, two Γ-shaped feeding structures and a ground. Meanwhile, the impedance bandwidth of the antenna is improved by folding the electric dipoles and loading the metal columns, while the beamwidth and port isolation are enhanced by loading additional electric dipoles and slotting the magnetic dipoles, respectively. Four parasitic patches are placed at the top to improve impedance matching of the antenna. By measurement, the overlapped relative bandwidth of two ports is 36.5% (2.87 GHz to 4.15 GHz). When port 1 is excited, the maximum beamwidths in E-plane and H-plane are 211° and 126°, respectively. When port 2 is excited, the maximum beamwidths in E-plane and H-plane are 208° and 127°, respectively. Therefore, the antenna has a wide application prospect in the 5G base station.
期刊介绍:
IEEE Antennas and Wireless Propagation Letters (AWP Letters) is devoted to the rapid electronic publication of short manuscripts in the technical areas of Antennas and Wireless Propagation. These are areas of competence for the IEEE Antennas and Propagation Society (AP-S). AWPL aims to be one of the "fastest" journals among IEEE publications. This means that for papers that are eventually accepted, it is intended that an author may expect his or her paper to appear in IEEE Xplore, on average, around two months after submission.
