A Broadband Dual-polarized Antenna for 2G/3G/4G/5G Base Station Applications
─ This paper presents a novel broadband base station antenna element covering 2G/3G/4G/5G bands. The proposed antenna consists of a dual-dipole radiator and an open-box shaped reflector. The main radiating portion of each dipole arm is designed with a dualhexagon shape to improve bandwidth. Four small hexagonal-shaped parasitic patches are adopted to further decrease the reflection coefficient. Dual polarization is excited by placing two dipoles orthogonally. The openbox shaped reflector derives from a planar metal plate with four inverted L-shaped edges which are arranged below the radiator to enhance the antenna gain and reduce the half power bandwidth (HPBW) in 3.3-3.8 GHz. The prototype has been fabricated and measured with bandwidth of 1.68-3.8 GHz, coupling below -20 dB, stable HPBW with 65°± 5° and average gain of 8.5 dBi. The values of the cross-polarization discrimination (XPD) are better than 20 dB at the boresight and 10 dB within ±60° directions. The proposed antenna has a small overall size of 145×145×35.6 mm. Index Terms ─ 5G antenna, base station antenna, broadband antenna, dual-polarized antenna.
期刊介绍：
The ACES Journal is devoted to the exchange of information in computational electromagnetics, to the advancement of the state of the art, and to the promotion of related technical activities. A primary objective of the information exchange is the elimination of the need to "re-invent the wheel" to solve a previously solved computational problem in electrical engineering, physics, or related fields of study.
The ACES Journal welcomes original, previously unpublished papers, relating to applied computational electromagnetics. All papers are refereed.
A unique feature of ACES Journal is the publication of unsuccessful efforts in applied computational electromagnetics. Publication of such material provides a means to discuss problem areas in electromagnetic modeling. Manuscripts representing an unsuccessful application or negative result in computational electromagnetics is considered for publication only if a reasonable expectation of success (and a reasonable effort) are reflected.
The technical activities promoted by this publication include code validation, performance analysis, and input/output standardization; code or technique optimization and error minimization; innovations in solution technique or in data input/output; identification of new applications for electromagnetics modeling codes and techniques; integration of computational electromagnetics techniques with new computer architectures; and correlation of computational parameters with physical mechanisms.
