高数据速率和抗干扰能力是必需的特征WLAN(无线Local Area网络)。多输入多输出(MIMO)天线系统作为一个有效的方式提高数据速率和增加WLAN的通道容量[1]吸引了相当大的利益。然而,MIMO无线局域网系统遭受严重的干扰问题,当越来越多的无线访问点(APs)已经部署或无线局域网用户的数量突然增加[2、3]。智能天线技术是一种有效的方法来克服这一缺陷[4、5]。转换梁和自适应波束形成数组是两个主要的智能天线技术。转换梁与定向天线阵列[6、7]简单的优势,因为几个固定梁可以选择通过控制大量的射频开关的状态减少干扰。比较自适应波束形成数组,转换梁阵列的简单性使得它适合于低成本、低功耗应用抗干扰MIMO无线局域网。

Abstract—Smart antennas have received increasing interest for mitigating interference in the MIMO WLAN. In this paper, a dual-band dual-polarized compact bowtie dipole antenna array is proposed to support anti-interference MIMO WLAN applications.In the antenna array, there are twelve antennas, six for horizontal polarization and six for vertical polarization. In order to achieve dual linear polarizations and beam switching, six horizontal antennas are placed in a sequential, rotating arrangement on a horizontal substrate panel with an equal inclination angle of 60° to form a symmetrical structure while the other six antennas for vertical polarization are inserted through slots made on the horizontal substrate panel. Besides, six pairs of meandered slits are introduced to reduce the mutual coupling between horizontal antennas in the lower band. A prototype of the array with a dimension of 150mm × 150mm × 60mm is manufactured and exhibits the characteristics of high isolation, good front-to-back ratio and average gains of 4.5 and 5dBi over the 2.4GHz and 5GHz band, respectively. The MIMO performance of the array is analyzed and evaluated by mutual coupling, the total active reflection coefficient (TARC) and the envelope correlation coefficient. The anti-interference capability of the array is also investigated by the experiment.

I. INTRODUCTION

IGH data rate and anti-interference capability are the necessary characteristics for the WLAN (Wireless Local Area Networks). Multiple-Input Multiple-Output (MIMO) antenna systems have attracted considerable interests as an effective way of improving the data rate and increasing the channel capacity in WLAN [1]. However, MIMO WLAN systems suffer severe interference problems, when more and more wireless access points (APs) have been deployed or the number of WLAN users are abruptly increasing [2, 3]. Smart antenna technology is an effective way to overcome this flaw......
