A Low-Profile Dual-Polarized Antenna with High Isolation and High Front-to-Back Ratio for 5G Base Stations
─ A dual-polarized, broadband, slot-coupled patch antenna design is presented for sub-6 GHz 5G base stations. Proposed antenna is made up of two suspended stacked patches above feedline layer and is excited by crossed elliptic-H slots for ±45o slant, linear dual polarized operation. Prototyped antenna has an impedance bandwidth of 22.1% (3.14 3.92 GHz) for S11, S22 < −15 dB and port isolation S21 is also obtained to be < −28 dB in this band. Antenna exhibits directional radiation patterns with half power beamwidths of 57o 65o and 60o 64o in elevation and azimuth planes, respectively with varying gain of 8.6 9.1 dBi. Proposed antenna is also low profile (11.1 mm) with high front-toback ratio (> 27 dB) without reflector. Design details, numerical studies, and measurement results are presented. Index Terms ─ Dual-polarized, broadband antenna, isolation, front-to-back ratio, sub-6 GHz 5G base stations.
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The ACES Journal welcomes original, previously unpublished papers, relating to applied computational electromagnetics.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.
