摘　　要：设计一种应用于无线局域网的单极子天线,天线上表面以矩形环和＂T＂形结构作为辐射单元,下表面则以矩形结构作为接地面。通过软件仿真和实验分析得出,这种天线工作频率范围分别为2.04～2.98 GHz和4.85～6 GHz,在工作频率范围内表现出良好的辐射特性。根据IEEE802.11规定的无线局域网频段范围,这种天线满足实际应用要求。A mono-pole antenna is designed in this paper. It can be applied in wireless local area network（WLAN）. The top surface of this antenna adopts rectangular ring and T- shape as radiation elements, and the bottom uses rectangular structure as ground plane. According to the simulation of software and analysis of experiment, the results show that the frequencies cover 2.45 GHz, 5.2 GHz and 5.8 GHz. This antenna can be satisfying in the actual applications as IEEE802.11 standard on the WLAN.
