摘要

报道了一种用于MIMO无线局域网的新型小尺寸双频双极化天线阵列。所述阵列元件包括具有领结偶极子的周期天线和具有反射器和定向器的印刷偶极子天线。该设计的特点是双频工作,前后比良好,在2.4 GHz和5.2 GHz频段上的平均增益分别为4和5 dBi。原型12元阵列在2.25GHz-2.6GHz和4.95GHz-6GHz之间具有双宽带和低互耦特性。测试结果表明,该阵列适用于采用MIMO和波束选择技术的802.11a/b/g/n系统。

Dual-band dual-polarized antenna array for beam selection MIMO WLAN
A novel compact size dual-band dual-polarized antenna array for MIMO WLAN is reported. The array element comprises a periodic antenna with bowtie dipoles and a printed dipole antenna with a reflector and a director. The presented design is characterized by dual-band operation, good front-to-back ratios, average gains of 4 and 5 dBi over the 2.4 and 5.2 GHz bands respectively. A prototype 12-element array exhibits dual broad bandwidth and low mutual coupling among 2.25GHz–2.6GHz and 4.95GHz–6GHz. The measured results indicate the array is suitable for 802.11a/b/g/n systems employing MIMO and beam selection techniques.
