Abstract

ABSTRACT This paper presents the 3D prism-shaped circularly polarised MIMO Diversity Antenna with 360° angular coverage. The proposed antenna has six elements, and it covers the X-band with impedance matching from 8.0 to 11.8 GHz (38.4%), 3 dB axial ratio from 8.05 to 10.6 GHz (27.34%). A metallic copper cylinder is placed inside the prism to improve the isolation and axial ratio. All the antennas are highly isolated, with isolation is more diminutive than −20.5 dB, except the adjacent element to the edge of the prism, for which it is −14.7 dB. The Envelope Correlation Coefficient (ECC) is less than 0.035. The proposed antenna structure shows the pattern or angle diversity in the whole 360° angle with polarisation diversity.

具有360度角覆盖的三维棱柱形圆极化MIMO分集天线

摘要本文介绍了一种360°角覆盖的三维棱镜形圆偏振MIMO分集天线。所提出的天线有六个元件，覆盖X波段，阻抗匹配范围从8.0到11.8 GHz（38.4%），轴比为3 dB（8.05到10.6 GHz（27.34%））。在棱镜内部放置一个金属铜圆柱体，以提高隔离度和轴比。所有天线都是高度隔离的，隔离度比−20.5 dB更小，除了棱镜边缘的相邻元件，其隔离度为−14.7 dB。包络相关系数（ECC）小于0.035。所提出的天线结构在具有极化分集的整个360°角中显示出方向图或角度分集。
