Abstract

A tri-band dual-polarized shared-aperture antenna array is proposed, in which a rotated double M-shaped branch (DMB) and four pairs of stubs are designed to suppress the scattering effect of low-band radiation. This antenna array consists of two low-band (LB) antennas and four mid/high-band (M/HB) antennas. The principle of rotated DMB is explained. The measured results show that the aperture-shared antenna array achieves impedance bandwidths of 51.0% (1.6 GHz to 2.7 GHz), 16.2% (3.46 GHz to 4 GHz), and 8.3% (4.6 GHz to 5 GHz). Good decoupling characteristics are observed. The isolation of LB exceeds 25 dB, MB exceeds 20 dB, and HB is more than 30 dB, achieving a good level of isolation. Moreover, very stable radiation patterns are achieved over the whole band, which could be a good candidate for modern base station applications.

用于基站的三波段双极化共孔径天线阵列

提出了一种三波段双极化共享孔径天线阵列，该天线阵列采用旋转双m型支路（DMB）和四对短节抑制低波段辐射的散射效应。该天线阵由2个LB （low-band）天线和4个M/HB （mid/high-band）天线组成。阐述了旋转DMB的原理。测量结果表明，孔径共享天线阵列的阻抗带宽分别为51.0% （1.6 GHz ~ 2.7 GHz）、16.2% （3.46 GHz ~ 4 GHz）和8.3% （4.6 GHz ~ 5 GHz）。观察到良好的去耦特性。LB的隔离度超过25 dB， MB的隔离度超过20 dB， HB的隔离度超过30 dB，达到了良好的隔离水平。此外，在整个频段内实现了非常稳定的辐射方向图，这可能是现代基站应用的良好候选者。

期刊介绍： IEEE Antennas and Wireless Propagation Letters (AWP Letters) is devoted to the rapid electronic publication of short manuscripts in the technical areas of Antennas and Wireless Propagation. These are areas of competence for the IEEE Antennas and Propagation Society (AP-S). AWPL aims to be one of the "fastest" journals among IEEE publications. This means that for papers that are eventually accepted, it is intended that an author may expect his or her paper to appear in IEEE Xplore, on average, around two months after submission.
