Abstract

A compact MIMO antenna with S- and WLAN bands is presented. The single element of the MIMO antenna is excited by a microstrip feed-line and a rectangular defected ground plane. A stepped feed-line is used to improve the impedance matching. Each working band is generated by using a stepped open-end meander line. To reduce mutual coupling and correlation, the MIMO elements are orthogonal to each other. The first band is 2.61-3.33GHz (720MHz, 22.8%) and the second band is around 3.92-10GHz (6080MHz, 86.9%). The antenna size is 20mm×40mm. The proposed MIMO antenna, besides its small size, has an omnidirectional pattern at operating frequencies.

用于s波段和WLAN应用的小型双频MIMO天线

提出了一种具有S波段和WLAN波段的小型MIMO天线。MIMO天线的单元件由微带馈线和矩形缺陷地平面激励。阶梯式馈线用于改善阻抗匹配。每个工作带都是通过使用阶梯式开口曲线生成的。为了减少相互耦合和相关，MIMO元素彼此正交。第一频段为2.61-3.33GHz (720MHz, 22.8%)，第二频段约为3.92-10GHz (6080MHz, 86.9%)。天线尺寸为20mm×40mm。所提出的MIMO天线除体积小外，在工作频率上具有全向方向。
