摘　　要：本文设计了一种工作在WLAN频段的4元多端口缝隙阵列天线.天线单元由微带馈线和刻蚀有弯折形缝隙的接地板组成,通过阵列天线解耦表面(ADS)降低单元间的互耦.天线的尺寸为55mm×160mm×24.1mm.仿真结果表明阵列天线能够工作在WLAN的2.4GHz工作频段,阻抗带宽为2.345~2.533GHz,单元之间的隔离度大于15dB,天线具有良好的辐射特性.A four elements multiport slot array antenna for WLAN band is proposed. The antenna element consists of a microstrip feed line and a ground plane etched with a folded slot, and the mutual coupling between the elements is reduced by the array-antenna decoupling surface(ADS). The overall size of the antenna is 55 mm×160 mm×24.1 mm. The simulationresults show that the array antenna can work in the 2.4 GHz frequency band of WLAN. The impedance bandwidth is 2.345~2.533 GHz, and the isolation between the antenna elements is greater than 15 dB. Also, the antenna has good radiation characteristics.
