摘要

正在开发的超宽带平面天线应该允许获得紧凑的可打印天线，它应该能够集成到低成本的系统中。它的缺点是其辐射方向图在某些频率上有空穴，并且其低频极限与接地面的大小有关。超宽带线贴片天线提供了相当干净的辐射方向图和良好的带宽匹配。与超宽带单极天线相比，其优点是结构紧凑。此外，它的带宽不依赖于地平面的大小。与可打印天线相比，其缺点是集成难度较大，成本较高。

Design of antennas for transient ultra wide band (UWB) systems

UWB planar antenna under development should allow to obtain a compact printable antenna which should be able to be integrated into low cost systems. Its disadvantages are holes at certain frequencies in its radiation pattern and a dependence of its low frequency limit with the size of ground plane. The UWB wire patch antenna offers a rather clean radiation pattern and a good matching on the bandwidth. Its advantage is a great compactness compared to antennas such as UWB monopole. Moreover its bandwidth does not depend on the size of the ground plane. Its disadvantage is a more difficult integration and a higher cost compared to printable antenna.
