摘要

本文提出了一种基于准自互补(QSC)元件的四元MIMO天线,该天线具有超宽带(3.1-10.6 GHz)特性,陷波带在WLAN上频段(5.15-5.85 GHz)。超宽带元件是梯形单极子,在地平面上具有互补切割。无线局域网的陷波特性是利用这些超宽带单极子的狭缝切割来实现的。元素的正交放置提供了模式多样性特性和高元素间隔离。在MIMO天线样机上进行了实验验证。

A quasi self-complementary UWB MIMO antenna having WLAN-band notched characteristics
In this paper, a four-element MIMO antenna based on quasi-self-complementary (QSC) elements is proposed, which has ultra-wideband (UWB) characteristics (3.1–10.6 GHz) with notch-band in upper WLAN frequency range (5.15–5.85 GHz). The UWB elements are trapezoidal shaped monopoles having complementary cuts in the ground plane. The WLAN-band notched feature is realized by use of slit-cuts from these UWB monopoles. Orthogonal placement of elements provides the pattern-diversity characteristics and high inter-element isolation. The proposed concept is validated by experimental measurements on fabricated MIMO antenna prototype.
