Abstract

© 2018, Electromagnetics Academy. All rights reserved. This paper proposes a new design of reconfigurable three-sector dual-mode dual-polarized antenna for use primarily in mobile communication base stations. The design offers the flexibility to be used as a sectorial (directive) or omnidirectional base station antenna whenever required. The two different radiating modes (omnidirectional and sectorial) depend only on the excitation scenario. The proposed antenna has the advantages of offering broadband, stable radiation pattern and high polarization purity within the desired frequency band, and a simple feeding structure with a very compact size (less than 800 cm3) and low profile. The achieved fractional bandwidth is 55.3% (1.7 - 3GHz). A prototype antenna was constructed and tested with the two modes of operation. Results demonstrate the principle of the design and show how the design may be packaged in a compact size to offer excellent omnidirectional or sectorial performance which makes this new design an ideal candidate for reconfigurable dual-mode mobile base stations.

用于扇区/全向移动基站的可重构宽带双模双极化天线

©2018，电磁学研究院。版权所有。本文提出了一种新的可重构三扇区双模双极化天线设计方案，主要用于移动通信基站。该设计提供了灵活性，可以在需要时用作扇形(指令)或全向基站天线。两种不同的辐射模式(全向和扇形)仅取决于激励情景。该天线具有宽带、稳定的辐射方向图和所需频带内高极化纯度的优点，并且馈电结构简单，尺寸非常紧凑(小于800 cm3)，外形小巧。实现的分数带宽为55.3% (1.7 - 3GHz)。搭建了天线样机，并在两种工作模式下进行了测试。结果证明了设计的原理，并展示了如何将设计封装在紧凑的尺寸中，以提供出色的全向或扇区性能，这使得这种新设计成为可重构双模移动基站的理想候选。
