Abstract

A small, loop-type ground radiation antenna for 2.4-GHz WLAN applications in the complex ground with two vertically attached printed circuit boards (PCBs) was designed. In the presence of a vertical PCB (sub-PCB), the antennas in two different positions, far from and near the sub-PCB, were designed. The current distribution of the complex PCB was stronger near the sub-PCB. Therefore, the coupling between the antenna and the complex PCB was stronger when the antenna was located near the sub-PCB. The antenna close to the sub-PCB obtained more than twice the 3:1 VSWR bandwidth and the efficiency bandwidth than the distant antenna.

垂直连接PCB的改进地面辐射天线性能

设计了一种小型环形地辐射天线，用于2.4 ghz复杂地面环境下的无线局域网应用，该天线采用两片垂直连接的印刷电路板(pcb)。在垂直PCB(子PCB)存在的情况下，设计了远离子PCB和靠近子PCB两个不同位置的天线。复合PCB的电流分布在子PCB附近更强。因此，当天线位于子PCB附近时，天线与复合PCB之间的耦合更强。靠近子pcb的天线获得的VSWR带宽和效率带宽是远端天线3:1的两倍以上。
