| 摘 要： | 用于短距离高速无线通信的超宽带天线,不仅要有较小的尺寸,还要求较小回波损耗和良好的全向性.环形开口共面波导馈电结构可增大电流路径、实现天线的小型化,叉形主辐射单元渐变结构使天线在全频段内、特别是高频段向各方向均匀辐射.仿真结果表明,天线在3.1 GHz～10.9 GHz频带内回波损耗小于-10dB、驻波比小于2,H面方向图直到9.5 GHz仍近似为圆形.天线结构紧凑,是一种高性能的低剖面小型化超宽带天线.

| Abstract: | UWB antenna used for short - range and high - speed wireless eommnieation requires not only smaller Size, but also smaller return loss and good omnidirectional. Structure of feed waveguide with annular opening coplanar can enhance current path and realize the miniaturization of antenna. Gradient structure with fork main radiating element owns the capability for creating homogeneous ra- diation of full band and high frequency in all directions particularly. The result shows that antenna in 3.1 GHz - 10.9 GHz owns return loss less than - 10db and VSWR less than 2. Figture of H fiat is still nealy a circle at 9.5GHz. The structure of proposed antenna is a miniaturizated one and it performs excellently in low profile ultra- wideband as well. |
