摘要
结合分形结构和加载缝隙的特性,提出一种多频段天线的设计方法。通过在具有分形结构微带天线的接地板上加载双U形缝隙,在单层微带天线上实现了多频段工作。分形结构的应用,降低了天线的谐振频率,该天线尺寸是未加分形天线尺寸的52%。在接地板加载双U形缝隙,改变了天线的电流路径,通过改变U缝隙的参数,可以灵活调整天线的谐振频率。根据天线设计的思路,通过分析、仿真及实测表明,该天线能工作在GSM900/GPS/DCS1800/TD-SCDMA 4种网络模式下。
Combined with fraction and slot added characteristic, a design of multiband antenna is introduced. Through adding dual U-shape slot to the ground-of fractal microstrip antenna, multiband working mode is realized on single layer microstrip antenna. For the application of fractal structure, the resonant frequency is reduced, and its size is 52 percent of the antenna without fraction. In addition, the current route of the antenna is changed, and the resonant frequency can be adjusted flexibly by changing the parameter of the dual U-shape slot. According to the design process combined with analysis,simulation and measurement, four network working modes including GSM900/GPS/ DCS1800/TD-SCDMA are shown.
