摘　　要：提出了一种新型的宽频带微带天线,辐射贴片基本结构为双同心圆环,选用环氧玻璃纤维树脂材质的基板,基板厚度H=1.6mm。将天线结构印制于30mm×40mm的基板上,同时参考地印制于基板背面选定区域。借助Ansoft HFSS 15.0进行仿真,在1~8GHz进行扫频,可用频段为2.44~5.40GHz,相对带宽为76%。给出了反射系数S_(11)、电压驻波比VSWR和辐射方向图的仿真结果,分析了结构参数R_1、R_2、O、W、H_1对天线辐射性能的影响。所设计天线基本可用于(2.40~2.48GHz/5.15~5.35GHz)WLAN、蓝牙、ZigBee、(3.40~3.69GHz/5.25~5.85GHz)WiMAX,具有一定的参考价值。A novel broadband microstrip antenna has been presented. The proposed double- ring antenna structure was printed on a fiber glass epoxy resin substrate. The thickness and area of the PCB were 1.6 mm and 30 mm×40 mm. Reference ground of the PCB was printed on se- lected region on the back of the substrate. With the simulation by the Ansoft HFSS 15.0 soft- ware, an available frequency band of 2.44-5.40 GHz with a relative bandwidth of 76% was ob- tained through sweeping frequency from 1 to 8 GHz. The simulation results of the reflection coef- ficient $11, VSWR and radiation pattern of the antenna were given, and the influence of parame- ters R1, R2, O, W, H1 on the return loss and bandwidth of the antenna were analyzed. The de- signed antenna has a certain reference value for the applications such as （2.40-2.48/5.15-5.35 GHz） WLAN, bluetooth, ZigBee, （3.40-3.69/5.25-5.85 GHz） WiMAX.
