摘要
针对超宽带系统对天线小型化及宽带化的要求,基于平面单极天线模型,采用辐射单元开圆形槽及缺陷接地板结构,提出了一种反L形接地板结构的超宽带平面天线。仿真分析表明,该天线谐振特性良好,阻抗带宽达到了12 GHz,同时天线体积仅为20 mm×20 mm×1.6 mm,实现了小型化,且结构简单,易于加工及集成,适合未来无线通信发展的需求。
According to the demands of the miniaturization and wideband of the UWB antenna, a new UWB antenna with inverted L-shaped groundplane is proposed using the slots which are cut off on the surface of the groundplane and the radiator based on the theory of the planar monopole antenna. The sim^a- tion shows that the antenna has a good resonance characteristic and a broad bandwidth with 12 GHz. As a result of the miniaturization, the size is 20 mm× 20 mm × 1.6 mm. The structure is simple and easy to process and integrate. The antenna fits the future demand of the wireless
