Abstract

─ 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.

面向5G基站的高隔离、高前后比的低轮廓双极化天线

─提出了一种适用于6 GHz以下5G基站的双极化宽带槽耦合贴片天线设计。该天线在馈线层上方由两个悬浮堆叠的贴片组成，由交叉椭圆- h槽激励，进行±45°倾斜线性双极化工作。样机天线在S11、S22< - 15 dB时阻抗带宽为22.1% (3.14 - 3.92 GHz)，端口隔离S21也在该频段< - 28 dB。天线在仰角面和方位面分别呈现出570 ~ 650°和600 ~ 640°的半功率波束定向辐射方向图，变化增益为8.6 ~ 9.1 dBi。拟议的天线也是低轮廓(11.1毫米)，具有高前后比(> 27 dB)，没有反射器。介绍了设计细节、数值研究和测量结果。索引术语─双极化、宽带天线、隔离、前后比、低于6 GHz的5G基站。

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 The ACES Journal welcomes original, previously unpublished papers, relating to applied computational electromagnetics.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.
