Abstract

A low profile ultra-wideband tightly coupled dipole array is studied. The antenna elements are fed by Marchand baluns of small size and low cost. A metasurface based wide-angle impedance matching (MSWAIM) layer is introduced to replace the traditional dielectric WAIM, improving the beam scan performance and reducing the antenna profile. The simulation shows that the proposed antenna array can operate over 2.4-12.4 GHz, approximately 5:1 bandwidth with maximum scanning angle of 50o for both E plane and 45o for H plane. The antenna profile above the ground is only 0.578λH at the highest operating frequency. This antenna array can find its application in the forthcoming massive MIMO beamforming systems for 5G.

一种具有元表面广角阻抗匹配的宽带宽扫描紧密耦合偶极子阵列

研究了一种低姿态超宽带紧密耦合偶极子阵列。天线单元采用体积小、成本低的马尔尚平衡馈电。提出了一种基于超表面的广角阻抗匹配层(MSWAIM)来取代传统的介电广角阻抗匹配层，提高了波束扫描性能，减小了天线轮廓。仿真结果表明，该天线阵列工作频率为2.4 ~ 12.4 GHz，带宽约为5:1,E面和H面最大扫描角分别为50o和45o。在最高工作频率下，地面上的天线轮廓仅为0.578λH。该天线阵列可以在即将到来的5G大规模emimo波束形成系统中得到应用。

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 The ACES Journal welcomes original, previously unpublished papers, relating to applied computational electromagnetics.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